Want to try tracking down some of the rarest blooks available on the educational Blooket platform? Blooket is full of colorful collectibles (plus games and events through which you can win them), with numerous blooks—characters or avatars that players can use—available to unlock. Of course, some blooks are harder to find than others. In this article, we’ll give you a thorough introduction to the rarest blooks in Blooket and how to obtain them.

What is the Rarest Blook in Blooket?

- Rarity: Chroma
- Obtainment: Available in the Safari Pack (from the market).

- Rarity: Legendary
- Obtainment: Available in the Aquatic Pack (from the market).
10
Mega BotThe Mega Bot blook is the second-rarest of the legendary blooks, with a 0.3% drop rate and a selling price of 200 tokens (although, technically speaking, it’s tied in terms of drop rate with the Tyrannosaurus Rex, King of Hearts, and Captain Blackbeard blooks).
