If you collect Blooks in Blooket, you have probably wondered which one is actually the hardest to find. Blooket has several rarity levels, from Common and Uncommon Blooks to Legendaries, Chromas, Uniques, and Mysticals. Because different Blooks are obtained in different ways, determining the “rarest” Blook depends on whether you mean the lowest pack drop rate, the fewest legitimate owners, or the highest overall rarity.
For players asking what is the rarest blook in blooket, one name stands out when considering legitimately obtainable event rewards: Tim the Alien. It is a Mystical Blook, and available information indicates that only two players obtained it through the Pokémon Are Cool event. Mysticals are the highest Blooket rarity and are awarded through special events rather than ordinary Market packs.
However, there is another important answer if you are specifically talking about Blooks that can be obtained from packs. In that category, Elf Sweater Snowman is notable because it had an exceptionally tiny 0.01% drop rate during its limited Blizzard Pack availability. That makes the distinction between the rarest Blook overall and the rarest pack Blook especially important.
What Is the Rarest Blook in Blooket?
So, what is the rarest blook in blooket? The answer depends on the definition of rarity, but Tim the Alien is generally identified as the rarest legitimately obtained Blook because of its extremely limited distribution. It belongs to the Mystical rarity, which sits above Uniques and Chromas in Blooket’s rarity system. Unlike normal Blooks that players can repeatedly attempt to obtain from Market packs, Mysticals are tied to special events and achievements.
Tim the Alien was associated with the Pokémon Are Cool event. According to the available Blooket community documentation, only two players obtained it because the event’s first-place players tied. This makes its scarcity different from a low percentage pack drop. A Blook with a 0.01% drop rate can theoretically be obtained by many players over time, while an event-exclusive reward may have a strictly limited number of winners.
Why Tim the Alien Is So Rare
The biggest reason Tim the Alien is so difficult to find is its method of distribution. It wasn’t simply sitting inside a Market pack waiting for players to spend tokens. Mysticals are awarded through Blooket events, meaning ownership is connected to special competitive or promotional opportunities.
Blooket’s Mystical category includes only a small number of Blooks, and these Blooks are no longer normally obtainable through the Market. The available documentation identifies Mysticals as the highest rarity and notes that Tim the Alien is the rarest Mystical based on its extremely small number of legitimate owners.
Understanding Blooket Rarity Levels
To understand what is the rarest blook in blooket, it helps to understand how Blooket’s rarity system works. Blooks are divided into several categories, and each category represents a different level of scarcity or method of obtaining the Blook.
| Rarity | General availability | Example |
|---|---|---|
| Common | Normally available | Standard Blooks |
| Uncommon | Market packs | Various themed Blooks |
| Rare | Market packs | Pack-specific Blooks |
| Epic | Market packs | Higher-tier pack Blooks |
| Legendary | Very low pack chances | Megalodon |
| Chroma | Extremely low pack chances | Elf Sweater Snowman |
| Unique | Special requirements | Wise Owl |
| Mystical | Special events | Tim the Alien |
The important point is that rarity does not always mean the same thing as drop probability. A Legendary may have a published percentage such as 0.2%, while a Mystical may not have any percentage at all because it isn’t randomly selected from a normal pack. Blooket’s documented rarity structure places Mysticals above Uniques and Chromas.
The Rarest Pack Blook: Elf Sweater Snowman
If your question means the rarest Blook that was actually available through a regular Blooket pack, the answer changes. Elf Sweater Snowman had a 0.01% chance of being obtained from the Blizzard Pack. The Blook was released as a limited Christmas-season Chroma and was only available for a short period.

This extremely low percentage is important because 0.01% is approximately one chance in 10,000 per pack opening, assuming the published rate is interpreted directly as a probability. Even after opening many packs, players could go without receiving it because each opening is still a separate chance.
The Chroma rarity itself is already extremely difficult to obtain from packs. Current community documentation places ordinary Chroma drop rates within a range of approximately 0.08% to 0.01%, depending on the particular Blook. That makes Elf Sweater Snowman an especially interesting example for collectors who measure rarity through pack odds.
Why Limited Availability Matters
Drop rate isn’t the only factor that determines how difficult a Blook is to own. Availability matters too. A Blook with a very low probability but long-term availability can potentially reach more collections over time than a Blook that was available for only a short period.
Elf Sweater Snowman combines both factors. It had an exceptionally low drop rate and was only available during a limited Blizzard Pack period. The Blooket Wiki identifies it as having a 0.01% drop rate and describes it as the rarest Blook released through that pack category.
How Rare Are Chroma Blooks?
Chromas are among the most interesting Blooks for collectors because they are much harder to receive from normal packs than Legendary Blooks. The documented Chroma drop-rate range is approximately 0.08% to 0.01%, although certain special Chromas have different acquisition methods.
For comparison, the rarest standard Legendary is Megalodon, which has a 0.2% drop rate in the Aquatic Pack. That means even the rarest Legendary has a considerably higher published chance than a Chroma such as Elf Sweater Snowman.
This explains why players sometimes answer what is the rarest blook in blooket with a Chroma when they are specifically discussing Market packs. It is a reasonable answer within that narrower category, but it doesn’t necessarily make that Blook the rarest Blook overall.
What Makes Mystical Blooks Different?
Mysticals are different from most other Blooks because their scarcity isn’t primarily based on random probability. They are connected to special Blooket events, and the number distributed can be extremely limited.
According to available documentation, Mysticals have a Blook Score of 75 and can sell for 1,000 tokens, although their real collector value is primarily associated with their rarity and acquisition history. Several Mysticals have been awarded through special events, including the Contest of Candy and Pokémon Are Cool event.
This is why simply comparing percentages doesn’t work when discussing the rarest Blook. A pack Blook might have a one-in-10,000 chance, while an event Blook might have been awarded directly to only a tiny number of players.
How Players Can Think About Blook Rarity
There are several different ways collectors can define “rarest.” Understanding these categories makes Blooket’s collection system much easier to follow.
- Rarest overall rarity: Mysticals sit at the top of the rarity hierarchy.
- Rarest known legitimate event Blook: Tim the Alien is associated with only two legitimate owners.
- Rarest pack drop: Elf Sweater Snowman had a 0.01% published drop rate.
- Rarest Legendary: Megalodon has a 0.2% drop rate.
These distinctions are useful because Blooket’s collection system contains Blooks obtained through packs, events, special requirements, seasonal opportunities, and other methods. Treating all of them as if they were acquired through the same system can produce a misleading answer.
Can You Still Get the Rarest Blooks?
For collectors, availability is just as important as rarity. Many of the rarest Blooks are no longer normally obtainable. Mysticals, for example, are associated with past events, while certain seasonal and retired Chromas are no longer available in their original packs.

That means having a large number of tokens does not necessarily allow a player to obtain every rare Blook. Tokens can help with Market packs when the desired Blook is currently available, but they cannot automatically recreate a past event or obtain an event-exclusive reward.
Players should therefore distinguish between rare, currently obtainable, and retired. A Blook can be exceptionally rare because only a few players received it, while another can be rare because it had an extremely low probability during a limited-time release.
Why Rare Blooks Are Important to Collectors
Rare Blooks have become an important part of Blooket’s collection experience because they provide an additional goal beyond simply playing games. Some players enjoy completing themed collections, while others focus on obtaining Chromas, Legendaries, Uniques, or event-exclusive Blooks.
The appeal is also connected to the story behind each Blook. A limited Blook can represent participation in a particular event or a successful pack opening from years earlier. As a result, two Blooks with different acquisition methods can both be highly interesting to collectors even if their official rarity categories are different.
Final Answer: What Is the Rarest Blook in Blooket?
So, what is the rarest blook in blooket? If “rarest” means the Blook with an exceptionally limited number of legitimate owners, Tim the Alien is the standout answer. It is a Mystical Blook associated with the Pokémon Are Cool event, and available documentation states that only two players obtained it. If you mean the rarest Blook obtained from a regular Market pack, Elf Sweater Snowman is the key example, with a documented 0.01% drop rate during its limited Blizzard Pack availability. Ultimately, Blooket rarity has several dimensions. Mysticals represent the highest rarity tier, Chromas can have incredibly low pack probabilities, and limited events can restrict ownership to only a handful of players. That is why the answer to what is the rarest blook in blooket depends on whether you are measuring rarity by tier, ownership, drop rate, or availability.
