You've spent hours grinding tokens. You've opened more Medieval Packs than you can count, hoping for a King. Maybe you even snagged a Megalodon and felt like the richest player in your class for a week. But honestly? Those aren't even close to the top. When we talk about the rarest blook in Blooket, we are moving past the stuff you can just "buy" in the market.
We are talking about Blooks that only two people in the entire world own. Two. Think about that next time you’re annoyed about pulling another Old Boot.
Tim the Alien: The Crown Jewel of Rarity
If you want the definitive answer, Tim the Alien is the rarest blook in Blooket history. It’s a Mystical rarity blook, which is a tier above even the Chromas that people go crazy for. It looks like a little green guy (Tim) in a UFO beaming up a cow.
Why is it so rare? Because it wasn't in a pack. You couldn't get lucky with 20,000 tokens. It was the grand prize for the "Pokemon Are Cool" event. Only the people who finished in first place got it.
Because two players actually tied for first place during that specific event, there are exactly two Tim the Aliens in existence. Unless Ben (the Blooket creator) decides to hand out more—which he won't—that number is stuck forever. It’s the ultimate "I was there" trophy.
The Mystical Tier: Where Only Elites Live
Most players think Chromas are the peak. They see a Rainbow Panda or a Frost Wreath and think they’ve reached the endgame. But Mysticals are a different beast entirely. You can’t unbox them. You can't find them in a "4-day only" pack.
Here is the thing about Mysticals: they are all animated. While your legendary King just sits there looking smug, Mysticals actually move.
The Spooky Ghost
This one is legendary for all the wrong reasons. It was the first-place prize for the original "Contest of Candy." It’s a blue, glowing ghost that hovers. For a long time, it was the "Big One." But since Blooket changed the event themes, it’s effectively retired. If you see someone using this in a Gold Quest lobby, they are either a Blooket OG or a very dedicated hacker.
Phantom King and Hamsta Claus
The Phantom King was the reward for the top two guilds in the "Potions of Pix’ahlia" event. It’s basically a King Blook but... well, ghost-like and terrifying.
Then you have Hamsta Claus. This one is kind of funny because it’s a reskin of the common Hamster. It was awarded to the top three players in the 2023 "Contest of Candy." Even though more people have it than Tim the Alien, it’s still rarer than any Chroma you’ll ever see.
What About the "Uniques"?
Blooket has another tier called Unique. These are weird because they aren't always hard to get, but they are limited by how you get them.
- Wise Owl: This was given to people who attended the ISTE 2023 conference in Philadelphia.
- Wise Caterpillar: This is actually one of the easiest "rare" blooks to get if you know the trick. You just had to import a question set from Khan Academy using their AI feature.
So, while "Unique" sounds fancy, a Wise Caterpillar doesn't carry the same weight as a Rainbow Astronaut. The Rainbow Astronaut was awarded to the winning team of the "LUNCH" event. Only about 25 people have it. It’s the only blook in the game that actually changes colors while you look at it.
The Rarest Blooks You Can Actually "Pull"
Let's be real: you probably aren't winning a global Blooket tournament next week. You want to know what you can actually get from the market.
If we are talking about drop rates, the Megalodon is the toughest Legendary to pull at a 0.2% chance. That’s 1 in 500 packs. But even that is "common" compared to Chromas.

Most Chromas, like the White Peacock or the colored Astronauts, have a drop rate of 0.05%. That is 1 in 2,000 packs. You could spend 50,000 tokens and still come up empty. It happens all the time. People lose their minds in Discord chats over this every day.
Why Does Rarity Even Matter?
It’s all about the Blook Score. Blooket recently revamped the "My Blooks" page to show off a score based on how rare your collection is.
Having a Mystical adds 75 points to your score. A Chroma adds less, but still way more than a Common. It’s a way for players to prove they aren't just casuals. Plus, there is a certain "fear factor" when you join a game of Crypto Hack and the person in the lead is rocking a Spooky Ghost. You just know they know the answers.
Actionable Tips for Collectors
If you want to actually start building a rare collection, stop wasting tokens on the basic packs every day.
First, save for seasonal events. Blooket almost always releases a limited-time pack around Halloween (Spooky Pack) or Christmas (Blizzard Pack). These contain Chromas that are only available for a few days.

Second, watch the "rotating" Chromas. Some blooks, like the different colored Astronauts, only appear on certain days of the week. Don't go blowing 5,000 tokens on a Tuesday if the color you want only drops on a Friday.
Lastly, participate in the global events. Even if you don't think you'll hit the top 10, the rewards for the top 100 or top 1,000 are often Chromas that will never be released again. That’s how you get the "rare" status without having to be a literal world champion.
