Catch a Brainrot drops you into a Roblox creature-collector from Indieun where you roam themed regions, fight the meme-inspired creatures wandering around, and add them to your roster after each win. The catchable roster is split across two regions right now, and every creature sits in one of four rarity tiers. Here is the full lineup.
Quick answer: There are 29 catchable Brainrots so far, spread across the Grass Zone (20) and the Ice Zone (9). Rarity runs Common, Uncommon, Rare, and Epic, with Epic being the highest tier currently in the game.
Rarity tiers in Catch a Brainrot
Every Brainrot belongs to one of four rarity tiers. Rarity gives you a rough sense of how tough a creature is to win against and catch, but each creature also has its own individual level worth watching. Starter-zone creatures go down easily, while higher rarities in later areas need better capture boxes.
| Tier | Notes |
|---|---|
| Common | Easiest to battle and catch; found early. |
| Uncommon | Slightly tougher; still early-game friendly. |
| Rare | Harder fights that reward better boxes. |
| Epic | Highest rarity in the game right now. |

How to catch Brainrots
Catching works the same way in both regions. When you enter a zone, Brainrots roam the area on their own. Walk up close to one to start a battle. Win the fight, and you get a chance to catch that creature and add it to your collection.
Regions are further split into early and late-game sections that open up once you find the secret keys scattered around the map. As you push into tougher areas, higher-rarity Brainrots become harder to secure, so upgrading your capture boxes matters more than it does in the starter grassland.
Note: The roster grows as more of the map is explored, so expect additional creatures and possibly higher rarity tiers to join these two zones over time.
