What Is the Rarest Blook in Blooket? A Complete Guide

Blooket has grown into much more than a classroom quiz platform. Alongside its question sets and game modes, collecting Blooks has become an important part of the experience. Players can build collections containing Common, Uncommon, Rare, Epic, Legendary, Chroma, Unique, and Mystical Blooks. While many can be obtained through packs or gameplay, a small group is connected to special events and extremely limited rewards. That is why collectors often ask about the rarest Blook in Blooket and which Blook is genuinely the hardest to own.

As of 2026, Tim the Alien is widely identified as the rarest Blook when rarity is measured by its original distribution and confirmed ownership. It is a Mystical Blook that was awarded to the tied first-place finishers of the Pokémon Are Cool event. Current reference material identifies only two original awarded copies, putting it in a different category from ordinary Blooks that players can obtain through packs.

However, there is an important detail that makes the subject more interesting. Tim the Alien can also appear as an extremely rare catch in Fishing Frenzy. Current game references list its Fishing Frenzy catch rate at 0.05%, the lowest rate in that mode. Therefore, there is a difference between the rarest Blook as a collectible and the rarest Blook players can encounter during gameplay.

What Is the Rarest Blook in Blooket?

The answer is Tim the Alien if the question is about the Blook with the most restricted original distribution. Tim the Alien belongs to the Mystical rarity category, which is positioned above the more familiar rarity levels such as Legendary and Chroma. Mystical Blooks are associated with special events rather than ordinary market-pack openings, making them fundamentally different from Blooks that can be obtained simply by spending tokens.

Tim the Alien was connected to the Pokémon Are Cool event, where two players tied for first place. Both received the special Mystical reward. Because the reward was tied to a particular competitive result rather than a normal pack probability, the supply was extraordinarily small. Current community reference sources continue to identify Tim as having two original awarded copies.

This limited distribution is the main reason the rarest blook in blooket is generally considered Tim the Alien. A player cannot simply save tokens and repeatedly open a regular pack until the original event reward appears. The Blook’s history is connected to a particular event, making its collectible status different from a Blook that has a tiny but repeatable drop rate.

Why Is Tim the Alien So Rare?

The biggest reason Tim the Alien is so unusual is its original acquisition method. Standard Blooks are commonly associated with packs, while special Blooks can be connected to events, achievements, or other limited opportunities. Mystical Blooks occupy an especially exclusive position because they have historically been awarded through special events. The Blooket Wiki currently lists five Mystical Blooks: Spooky Ghost, Tim the Alien, Phantom King, Rainbow Astronaut, and Hamsta Claus.

Tim’s original event distribution was exceptionally small. The Pokémon Are Cool event ended with a tie at the top, resulting in two players receiving the reward. That is very different from an item with a 0.05% or even 0.01% pack probability, because a pack-based Blook can potentially be obtained repeatedly by many players over time. Tim’s original award was restricted to a tiny group of event winners.

Another factor is that Mystical Blooks are animated. This gives them a distinctive visual identity compared with many standard Blooks. Tim the Alien is based around an alien/UFO design and includes an animated presentation, helping it stand out among Blooket collectibles.

Tim the Alien and Fishing Frenzy

There is a fascinating distinction between Tim the Alien’s collectible history and its appearance in Fishing Frenzy. Current Fishing Frenzy data lists Tim the Alien as an Angler’s Legend with a 0.05% catch rate. That makes it the lowest-probability catch in the mode according to current reference data.

This means players may encounter Tim during Fishing Frenzy even though the original event reward was extremely restricted. Community reports from 2026 also show players discussing successful Tim the Alien catches in Fishing Frenzy. These reports are useful for understanding the current gameplay experience, although community posts should not be treated as equivalent to official Blooket documentation.

The distinction matters because “rarest” can mean different things. If someone means the rarest original collectible based on historical distribution, Tim the Alien is the leading answer. If someone means the hardest Blook to encounter in a particular current game mode, the answer can depend on that mode’s catch or drop table.

What Are Mystical Blooks?

Mystical is the highest and most exclusive Blook rarity category described in current Blooket reference material. Unlike ordinary pack rarities, Mysticals have historically been connected to special events and competitive accomplishments. They are also notable because they are animated, which gives them an additional visual distinction.

There are currently five recognized Mystical Blooks in the commonly referenced collection. Spooky Ghost was associated with the original Contest of Candy, Tim the Alien came from Pokémon Are Cool, Phantom King was awarded through Potions of Pix’halia, Rainbow Astronaut was associated with the LUNCH event, and Hamsta Claus was connected with the 2023 Contest of Candy.

Their acquisition histories demonstrate why simply looking at pack percentages does not tell the entire story of Blooket rarity. A Chroma may have an extremely small drop chance, but players can potentially keep opening the relevant pack. A Mystical connected to a completed event can have a fundamentally different supply situation.

Tim the Alien vs. Spooky Ghost

Spooky Ghost is another major contender whenever players discuss the rarest blook in blooket. It was the first Mystical Blook and was awarded to first-place winners of the Contest of Candy. The Blooket Wiki describes it as a retired Mystical Blook and notes that its original event distribution was extremely limited.

The two Blooks therefore have something important in common: both are tied to historical events rather than normal pack collection. Their extremely limited origins make them valuable to collectors, but rarity claims can become complicated when exact ownership figures are not publicly maintained in a single official database.

Tim the Alien nevertheless stands out because current 2026 reference sources consistently identify it as having only two original awarded copies. That exceptionally small distribution is the key reason it is commonly named when people ask for the rarest Blook overall.

Other Extremely Rare Blooks

Not every rare Blook is Mystical. Blooket also has Chroma and Unique categories that can be difficult to obtain. Some Chroma Blooks have very small pack probabilities, meaning players can spend substantial amounts of tokens without receiving the desired item. Their rarity is therefore based on probability and availability rather than a tiny fixed historical distribution.

For example, current Blooket reference material identifies certain Chroma Blooks with very low individual probabilities. Some community-maintained data places specific Chroma opportunities around 0.02% or 0.05%, depending on the pack and Blook. These probabilities can change with pack availability and game updates, so they should not automatically be treated as permanent values.

Some important categories to understand are:

• Mystical: Historically associated with special events and exceptionally limited distribution.
• Unique: Special Blooks that are generally harder to obtain than ordinary Chromas.
• Chroma: Special variants that can have extremely low acquisition probabilities.
• Legendary: High-rarity Blooks that are generally more obtainable than Mysticals.

This distinction explains why a Blook with a tiny pack probability is not necessarily the same thing as the rarest Blook overall.

Can You Get the Rarest Blook in Blooket Today?

The answer depends on what “get” means. If you mean receiving Tim the Alien through the original Pokémon Are Cool event, that opportunity has ended. You cannot recreate the historical event result and receive the original event prize in the same way.

However, Tim the Alien has a current gameplay presence in Fishing Frenzy. Current data lists it at a 0.05% catch rate, making it an exceptionally uncommon encounter within that mode.

This is an important point for newer players. Seeing Tim the Alien appear during Fishing Frenzy does not necessarily mean the original event reward system has returned. Instead, the Blook can appear as part of the game’s Fishing Frenzy catch system. Community players have reported encountering it this way during 2026.

Why Collectors Care About Rare Blooks

Rare Blooks are interesting because they give players a way to demonstrate collection history. In many games, the rarest collectibles are simply the most expensive items. Blooket works differently because some of its most unusual Blooks are connected to events, achievements, and limited-time opportunities.

For collectors, an event-exclusive Blook can represent a particular moment in Blooket’s history. Tim the Alien is a good example because its original distribution was connected to a specific competitive event and an unusual tie for first place. Spooky Ghost has a similar historical appeal because it came from an early Contest of Candy event and became the first Mystical Blook.

That history also explains why rarity discussions can change over time. Blooket continues to add content and modify its game modes, while older events may remain closed. A new event-exclusive Blook could eventually become extremely scarce, while an older Blook could become more accessible if Blooket decides to bring it back.

How Blook Rarity Should Be Compared

When comparing Blooks, it is useful to look at more than just the label displayed in a collection. Rarity can refer to the official tier, the number of known owners, the probability of obtaining an item, or whether the item is currently available.

For example, Tim the Alien is classified as Mystical, while some Chromas can have extraordinarily low pack probabilities. A player opening packs may therefore spend a long time chasing a particular Chroma, while Tim’s original event distribution was limited to a tiny number of winners. These are two different kinds of rarity.

This is why the rarest blook in blooket is better understood through both historical distribution and current gameplay availability. Tim the Alien has the strongest claim when discussing overall collectible scarcity, while individual packs and game modes can have their own rarest obtainable Blooks.

Is Tim the Alien More Valuable Than Other Blooks?

Tim the Alien is notable for its rarity, but rarity and monetary value are not automatically the same thing. Blooket’s system is primarily built around collecting and gameplay rather than an official player-to-player marketplace where every Blook receives a freely determined market price.

Reference material lists Mystical Blooks with a sell value of 1,000 tokens and a Blook Score of 75, which are among the highest listed values associated with Blooks. However, these in-game values should not be interpreted as real-world cash values.

The appeal of Tim the Alien comes largely from its scarcity, history, appearance, and status within Blooket’s collection system. For someone interested in completing a collection, owning an exceptionally limited Blook can be much more significant than simply having a high token balance.

Conclusion

So, what is the rarest blook in blooket? As of 2026, Tim the Alien is the most commonly supported answer when rarity is based on its original distribution and extremely limited number of awarded copies. It belongs to the Mystical tier and was originally awarded to the tied first-place finishers of the Pokémon Are Cool event. Current reference sources identify two original awarded copies, which puts it in an exceptionally limited category. At the same time, Tim the Alien has an unusual current gameplay connection because it can appear as an extremely rare catch in Fishing Frenzy. Its 0.05% listed catch rate makes it the rarest catch in that mode, although this should be distinguished from its historical status as an event-awarded collectible.
