If you have ever opened a Blooket pack, watched the animation spin, and whispered, “Please be a Chroma,” congratulations: you understand the emotional roller coaster of Blook hunting. Blooket may be a classroom review game at heart, but its collectible characterscalled Blookshave created a whole side quest of rarity, flexing, and occasional token-related heartbreak.
So, what is the rarest Blook in Blooket? The best answer is Tim the Alien. It is a Mystical Blook, was awarded through a limited Blooket event, and only two players are widely recorded as having obtained it. That makes it rarer than normal pack Blooks, rarer than most Chromas, and rarer than that one student who says, “I studied,” and actually did.
However, ranking the rarest Blooks is not as simple as looking at drop rates. Some rare Blooks come from packs, some were awarded during special events, and some are no longer obtainable at all. This guide ranks the top 10 rarest Blooks in Blooket using three main factors: rarity tier, known owner count, and how difficult or impossible the Blook is to obtain today.
How Blooket Rarity Works
Blooket uses rarity tiers to organize Blooks. The common order generally moves from Common, Uncommon, Rare, Epic, Legendary, Chroma, Unique, and then Mystical. For everyday players, Chromas are usually the rarest Blooks that can be pulled from packs. For collectors, though, Mysticals and limited event Blooks are the real crown jewels.
The difference matters. A Chroma with a 0.01% drop rate is incredibly difficult to pull, but at least it may have been available through a pack at some point. A Mystical like Tim the Alien is different because it was never a normal pack reward. You could open packs until your mouse files for retirement and still not get one.
What Is the Rarest Blook in Blooket?
The rarest Blook in Blooket is Tim the Alien. It belongs to the Mystical rarity tier and is famous because only two players are known to have received it. It was awarded during the Pokémon Are Cool event, making it one of the most exclusive Blooks in the entire game.
For players asking about the rarest Blook that was released in a pack, the answer is different. The Elf Sweater Snowman is often considered the rarest pack-released Blook because it had a 0.01% drop rate and was only available for a limited time. But overall, event-only Mysticals still beat pack Blooks in true scarcity.
The Top 10 Rarest Blooks in Blooket Ranked
1. Tim the Alien
Rarity: Mystical
Known scarcity: Only two known owners
How it was obtained: Pokémon Are Cool event
Tim the Alien is the undisputed king of Blooket rarity. It is not just rare; it is “museum security should be involved” rare. Because it was awarded to only two players in a special event, it cannot be obtained through regular gameplay, market packs, or token grinding.
Its design is also memorable: a UFO-style alien theme that feels special even before you know the numbers. For collectors, Tim the Alien represents the highest level of Blooket exclusivity. If someone has it, they are not just luckythey were part of a tiny slice of Blooket history.
2. Spooky Ghost
Rarity: Mystical
Known scarcity: Extremely limited; only a few known owners
How it was obtained: Contest of Candy first-place prizes
Spooky Ghost is another legendarywell, technically Mysticalname in Blooket collecting. It was awarded to first-place winners of the Contest of Candy, and it is now retired. Because it is tied to old Halloween-themed competitions, Spooky Ghost carries both rarity and nostalgia.
It is also one of the animated Blooks, which makes it feel more premium than a standard character skin. The fact that it appears in multiple game-related contexts adds to its reputation. In the rare Blook world, Spooky Ghost is the collector’s haunted mansion: spooky, impressive, and probably impossible to move into.
3. Hamsta Claus
Rarity: Mystical
Known scarcity: Awarded to the top three players
How it was obtained: 2023 Contest of Candy
Hamsta Claus is what happens when holiday cheer meets extreme competition. This Mystical Blook was awarded to the top three players in the 2023 Contest of Candy. That makes it one of the rarest Blooks ever released, even though it is newer than classics like Spooky Ghost.
The design is festive, animated, and instantly recognizable. It is based on the Hamster Blook but dressed in a holiday theme, which gives it a fun personality. Do not let the cute look fool you, though. This tiny holiday hamster is rarer than most players’ chances of winning a class Kahoot after forgetting the topic.
4. Rainbow Astronaut
Rarity: Mystical
Known scarcity: Awarded to the top LUNCH event team
How it was obtained: LUNCH event
The Rainbow Astronaut is one of the flashiest rare Blooks in Blooket. It was awarded during the LUNCH event to the top team, and it is known for its color-changing appearance. Among rare Blooks, very few have the same visual “look at me” energy.
It is especially interesting because it connects to the Astronaut family of Blooks, which includes several Chroma versions. But the Rainbow Astronaut sits above them because it is Mystical, animated, and event-exclusive. If normal Astronaut Blooks are cool, Rainbow Astronaut is the one walking into the cafeteria with sunglasses indoors.
5. Phantom King
Rarity: Mystical
Known scarcity: Around 50 owners are commonly reported
How it was obtained: Potions of Pix’ahlia event
Phantom King is not as scarce as Tim the Alien or Spooky Ghost, but it is still wildly rare. It was awarded to top guilds in the Potions of Pix’ahlia event and remains one of the most recognizable Mystical Blooks.
Its design also gives it serious boss-level energy. The regular King is already one of Blooket’s most iconic Legendary Blooks, but Phantom King turns that royal theme into something darker and more exclusive. If you see it in someone’s collection, you are looking at a player who either competed at a high level or has a very impressive account history.
6. Lime Astronaut
Rarity: Chroma
Known scarcity: Awarded to the top three finishers
How it was obtained: Pokémon Are Cool event
Lime Astronaut is a Chroma, not a Mystical, but its owner count makes it one of the rarest Blooks in the game. It was awarded to the top three finishers in the Pokémon Are Cool event, which puts it in the same conversation as some Mysticals when it comes to scarcity.
Because Astronaut reskins are already popular, Lime Astronaut has extra collector appeal. It is bright, clean, and instantly recognizable. More importantly, you cannot simply grind tokens and expect to pull it from a pack. This is an event-awarded Chroma, which makes it much more exclusive than most pack Chromas.
7. Cyan Astronaut
Rarity: Chroma
Known scarcity: Awarded to the top 10 finishers
How it was obtained: Pokémon Are Cool event
Cyan Astronaut is another extremely rare event Chroma from the Pokémon Are Cool event. It was awarded to the top 10 finishers, making it more common than Lime Astronaut but still far beyond the reach of ordinary pack opening.
The Cyan Astronaut also benefits from the same collector demand as other Astronaut variants. The Astronaut family has become one of the most famous groups of rare Blooks, partly because the colors are easy to recognize and partly because players love anything that looks like it came from a space-themed trophy case.
8. Spooky Mummy
Rarity: Chroma
Known scarcity: Fewer than 20 owners are commonly reported
How it was obtained: Contest of Candy rewards
Spooky Mummy is a retired Chroma connected to the Contest of Candy. It was awarded to top players in earlier Halloween events, and because those events are over, the Blook is no longer obtainable through normal means.
Its rarity comes from a combination of low distribution and retirement. It also has strong seasonal appeal. Halloween Blooks tend to become collector favorites because they feel tied to specific memories, events, and limited-time competition. Spooky Mummy is not just rareit feels like a badge from an older era of Blooket.
9. Wise Owl
Rarity: Unique
Known scarcity: Fewer than 200 are commonly reported as still existing
How it was obtained: ISTE 2023 event in Philadelphia
Wise Owl is different from the event leaderboard Blooks because it was not awarded through a typical in-game contest. It was obtained by attending ISTE 2023 in Philadelphia and completing a related process at the Blooket booth. That real-world requirement makes it one of the strangest and most interesting rare Blooks.
As a Unique Blook, Wise Owl sits in a rarity tier above Chromas but below Mysticals. It is retired, meaning players cannot obtain it the same way today. Its collector value comes from scarcity, history, and the fact that it was connected to a real education technology event rather than a normal in-game pack.
10. Elf Sweater Snowman
Rarity: Chroma
Known scarcity: 0.01% pack drop rate during limited availability
How it was obtained: Blizzard Pack
Elf Sweater Snowman deserves a place on this list because it represents a different kind of rarity: brutal pack odds. With a 0.01% drop rate during its release window, it is widely considered one of the rarest Blooks ever released through a pack.
Unlike Mysticals, it was technically pullable. But “technically pullable” at 0.01% is the game’s way of saying, “Good luck, champion.” Players could spend huge amounts of tokens and still never see it. That makes Elf Sweater Snowman the rarest Blook for players who care specifically about market-pack luck rather than event awards.
Rarest Blook by Category
Rarest Overall Blook
The rarest overall Blook is Tim the Alien. Its tiny owner count and Mystical status put it at the top of the entire rarity pyramid.
Rarest Pack Blook
The rarest pack-released Blook is commonly considered Elf Sweater Snowman, thanks to its 0.01% drop rate and limited seasonal availability.
Rarest Legendary Blook
The rarest Legendary Blook is Megalodon, which has a 0.2% drop rate from the Aquatic Pack. It is much easier to obtain than a Mystical, but among Legendaries, it is the big shark in the small pond.
Rarest Obtainable Pack Type
Chromas are usually the rarest Blooks that players can chase through packs. Some pack Chromas have drop rates around 0.03%, 0.02%, or even 0.01%, depending on the pack and release period.
Why Rare Blooks Matter So Much
Rare Blooks do not automatically make someone better at answering questions. A player with a Common Blook can still win if they know the material. But rare Blooks matter because they create identity, history, and bragging rights. They are the digital equivalent of walking into class with limited-edition sneakers, except the sneakers are square and sometimes dressed like a ghost.
For many players, collecting rare Blooks is part of the fun. Opening packs gives the game an extra reward loop. Events create excitement. Seasonal releases make players check the market more often. Even when someone does not own a rare Blook, talking about them has become part of the Blooket community experience.
Can You Still Get the Rarest Blooks?
Most of the Blooks in the top 10 cannot currently be obtained. Tim the Alien, Spooky Ghost, Hamsta Claus, Rainbow Astronaut, Phantom King, Lime Astronaut, Cyan Astronaut, Spooky Mummy, and Wise Owl were tied to past events or special circumstances. Unless Blooket brings them back or introduces an official trading system in the future, they remain locked in history.
Pack-based rare Blooks are different. If a Blook returns in a seasonal pack, players may have a chance to pull it again. But retired pack Blooks may not come back, and even when they do, the drop rates can be painfully low.
Tips for Collecting Rare Blooks Without Losing Your Mind
First, understand the difference between obtainable and unobtainable Blooks. Do not waste tokens trying to pull a Mystical from a normal pack. That is not how the system works.
Second, save tokens for packs that actually contain the Blook you want. Randomly opening packs can be fun, but targeted collecting is smarter. If your goal is a Chroma, focus on the specific pack and learn the drop rate.
Third, participate in events when they happen. Many of Blooket’s rarest Blooks came from limited-time competitions. You may not win the grand prize, but events are often where the most interesting collectibles appear.
Finally, avoid hacks, fake generators, and suspicious “free rare Blook” offers. Real rarity is earned through official gameplay, events, or legitimate releases. If a website promises every Mystical in five seconds, it is probably trying to steal more than your enthusiasm.
Player Experiences: What Chasing the Rarest Blook in Blooket Actually Feels Like
Trying to collect rare Blooks in Blooket is a mix of strategy, patience, and dramatic overreaction. One minute you are calmly opening packs like a responsible digital citizen. The next minute you see a flash of unusual color and suddenly your entire personality becomes “Did anyone else see that?”
The first experience many players remember is pulling their first Epic or Legendary. It may not be one of the rarest Blooks in Blooket, but it feels huge at the time. Maybe it is the King, the Megalodon, or the Astronaut. Whatever it is, that first big pull teaches players why collecting is so addictive. It is not only about the Blook itself; it is about the surprise.
Then comes the Chroma chase. This is where things get serious. A player may save tokens for days, open the same pack repeatedly, and still get the same common Blook again and again. At some point, the pack starts to feel personal. You are no longer opening it for fun. You are opening it because the pack has disrespected your family name.
Event Blooks create a different experience. Instead of luck, they reward performance, timing, and sometimes teamwork. Players who competed in major Blooket events had to put in effort beyond normal classroom games. That is why Blooks like Tim the Alien, Phantom King, and Rainbow Astronaut feel so special. They are not just collectibles; they are proof that someone was there when something rare happened.
For newer players, learning about rare Blooks can feel both exciting and slightly painful. Exciting because the game has a deeper history than it first appears. Painful because many of the coolest Blooks are retired. It is like joining a club and discovering that the best hoodie was sold three years ago to five people and one of them may have framed it.
Still, that history is part of the fun. Rare Blooks give the Blooket community stories to tell. Players compare collections, discuss drop rates, remember old events, and debate which Blook deserves the top spot. Even if you never own Tim the Alien, knowing why it matters makes the game feel bigger.
The healthiest way to approach rare Blook collecting is to treat it as a bonus, not the whole game. Blooket is still about answering questions, learning, competing, and having fun. Rare Blooks are the shiny sprinkles on top. They look great, they make people jealous in a harmless way, and they give collectors something to chasebut they should not turn the game into a stress machine.
So if you are hunting rare Blooks, enjoy the process. Save tokens, watch for events, learn the odds, and celebrate small wins. Maybe you will never get a Mystical. Maybe you will pull a Chroma when you least expect it. Either way, every pack opening has that tiny moment of suspense, and that is exactly why players keep coming back.
Conclusion
The rarest Blook in Blooket is Tim the Alien, thanks to its Mystical rarity and extremely limited distribution. But the full rarity picture includes many fascinating names: Spooky Ghost, Hamsta Claus, Rainbow Astronaut, Phantom King, Lime Astronaut, Cyan Astronaut, Spooky Mummy, Wise Owl, and Elf Sweater Snowman.
If you are ranking by overall exclusivity, event-only Mysticals dominate the list. If you are ranking by pack odds, limited Chromas like Elf Sweater Snowman deserve serious respect. Either way, rare Blooks are a major reason Blooket has remained so fun to discuss, collect, and occasionally yell about when the pack gives you another duplicate.
