Catch a Brainrot launched on Roblox on July 10, 2026, and it has already become one of the platform’s biggest new hits. Developer Indieun built the game around a creature-collecting structure and filled it with Italian brainrot memes like Tung Tung Tung Sahur and Ballerina Cappuccina as the things you are actually hunting.
What makes ranking this one different from most creature collectors is that there are no elemental advantages between Brainrots. Typing does not decide matchups here. Everything comes down to the rarity of the Brainrot you catch and the abilities it rolls, since movesets are assigned randomly and cannot be rerolled. With more than 29 species confirmed across the Grass Zone and Ice Zone, knowing which starter, which abilities, and which Brainrots to prioritize makes a genuine difference from your first session.
What Is Catch a Brainrot?
Catch a Brainrot is a turn-based creature-collecting RPG where you pick a starter from the Rot Lab, explore themed zones, and catch, level, and battle Brainrots to fill your Brain Index. Every Brainrot belongs to one of four rarity tiers: Common, Uncommon, Rare, and Epic.
Abilities are assigned at random the moment you catch a Brainrot. Leveling it up increases how much damage or healing those abilities deal, but it never changes which abilities it has. The only way to get a specific ability on a specific species is to keep catching more of them until you find one that rolled what you need.
Progression is zone-locked. You clear the Grass Zone first, then unlock the Ice Zone. Later zones are gated behind crafting materials and secret keys hidden across each map, finding those keys is not optional if you want access to the best Brainrots in each area.
Rotboxes are the only capture tool in the game. Higher-tier Rotboxes directly improve your catch rate and are required for Rare and Epic Brainrots, especially in the late sections of each zone. Upgrade your Rotboxes before moving zones rather than after you arrive and fail a series of catches.
Best Starter Brainrot in Catch a Brainrot
Three starters are available at the Rot Lab, and all three are Common rarity, so there is no rarity advantage to consider.
Boneca Ambalabu and TungTungTung Sahur are the picks to make. Both come with Shield, currently the best defensive move in the game, and Bomb, a strong early offensive option, giving you coverage on both ends of a fight from the very first battle. Their performance is essentially identical, so the choice between them is purely personal preference.
Frulli Frulla rounds out the trio but starts with a weaker moveset. It is playable, but there is no competitive reason to choose it over the other two unless you specifically want the character.
Catch a Brainrot Ability Tier List
Because rarity does not gate which moves a Brainrot can roll, most of the actual tier list work in Catch a Brainrot happens at the ability level.
Every move has an Energy cost between 2 and 6. Charge is the only free action, generating 1 Energy per use.
Rankings below are based on energy efficiency, burst potential, and how well each move fits into a real three-move build.
| Tier | Abilities | Why |
|---|---|---|
| SSS | Whirlpool (6), Arm (5), Shield (2), Heal (2) | Whirlpool is the highest-damage move in the game and is most effectively fired right after eliminating a Brainrot when you pick up bonus Energy. Arm is the cheaper version of the same idea. Shield blocks all incoming damage for a full round at just 2 Energy. Heal pairs with almost any build to extend a Brainrot’s survivability |
| S | Shoot, Trident, Feathers, Splash (all 2) | The backbone economy moves. Whichever 2-cost damage move you roll, it fits into nearly every moveset and is always worth keeping |
| A | Sword, Bite, Wheel Attack, Zap, Bats, Fry (all 3) | Slightly less flexible than the 2-cost tier but efficient enough to build a moveset around |
| B | Grow a Garden (5), Fireworks, Match, Bomb, Fire Blast (all 4) | Strong in the early game. Grow a Garden in particular does double work by draining enemy health and restoring your own simultaneously, making it one of the most impactful moves in casual play and leveling |
| C | Mr Beast (3) | Deals less damage than other 3-cost moves for the same Energy cost |
Important note on Grow a Garden: There is active community debate on this ranking. Many experienced players rate Grow a Garden as the single strongest ability in the game because it effectively works as both an attack and a heal in one move at 5 Energy. The B-tier placement here reflects its position in an optimized Energy economy against endgame bosses, where cheaper options like Shield, Heal, and 2-cost damage moves outperform it on raw efficiency. For casual play and zone clearing, Grow a Garden is arguably S-tier. For competitive PVP and boss optimization, it falls behind.
Best Moveset Builds
- Defensive PVP: 2, 2, 3 or 4, one 2-cost as Shield or Heal, one 2-cost as a damage move, and a 3 or 4-cost for additional pressure. Shield forces initiative and wins clutch trades.
- Offensive PVP: 2, 3, 6: All damage moves. Spam 2-costs for Energy economy, use the 3-cost to tempo, and fire Whirlpool immediately after an elimination when you chain bonus Energy from the kill.
- PVE (bosses): 2-3-4 or 2-3-6, all damage moves. Alternatively, a 2-2-X split where one 2-cost is a damage move, the other is Heal, and X is your highest-cost finisher.
Two rules that apply to every build:
- Never stack three moves of the same Energy cost. Equal-cost builds have poor economy and fewer meaningful trade breakpoints
- Never build a moveset with no 2-cost move. You need that cheap damage or utility option as the backbone of your Energy economy regardless of what else you are running
Best Brainrots by Rarity
Even with random abilities, rarity matters. Higher-rarity Brainrots have better stat potential and a higher probability of rolling top-tier moves. Catching a new species for the first time also rewards Player XP based on rarity: 50 XP for Common, 75 for Uncommon, 100 for Rare, and 150 for Epic.
Epic is currently the highest rarity in the game. These are the ones worth prioritizing once you are geared up enough to take them on:
- Grass Zone Epics: Chicleteira Bicicleteira, Bombombini Gussini, Ecco Cavallo Virtuoso, Spijuniro Golubiro, and Orangutini Ananaini
- Ice Zone Epics: Lirili Larila and Strawberrelli Flamingelli
These Brainrots consistently outperform everything below Epic once leveled, making them the priority catches for your main team as you clear each zone. Remember to upgrade your Rotboxes before hunting them — catching Epics with starter-tier boxes wastes coins and attempts.
All Brainrots by Zone
Here is the full confirmed species list as of July 2026, split by zone. The late section of each zone is locked behind a secret key hidden on the map, find it before trying to access the full roster.
Grass Zone (20 species):
- Common: Glorbo Fruttodrillo, Flamingulli, Tric Trac Barabum
- Uncommon: Capyberelli Bananalelli, Pussini Sushini, Trippi Troppi, Salt, Pepper Shaker, Zibra Zubra
- Rare: Ballerina Cappuccina, TaTaTa Sahur, Avocadini Guffo, Rhino Tosterino, Perchello Lemonchello, Cappuccino Assassino
- Epic: Chicleteira Bicicleteira, Spijuniro Golubiro, Orangutini Ananaini, Ecco Cavallo Virtuoso, Bombombini Gussini
Ice Zone (9 species):
- Common: Penguino Cocosino, Quivioli Ameleonni
- Uncommon: Six Seven, Svinino Bombondino

That is 29 confirmed species across two zones. More will be added as later zones go live.
Final Thoughts
Catch a Brainrot is only in its first week, and with no elemental system driving matchups, ability rolls are doing the majority of the work when it comes to what actually wins fights.
Expect this tier list to shift as players push into World 2 and World 3 and as Epic-rarity stat potential gets tested more thoroughly. For now, hunting Shield, Heal, and Whirlpool on any Rare or Epic Brainrot is the safest foundation for a team that holds up across both zones.
Boneca Ambalabu and TungTungTung Sahur are the strongest starters. Both come with Shield and Bomb, giving you defensive and offensive coverage from the first battle. Their performance is identical, so the choice between them is personal preference.
No. Abilities are assigned randomly when you catch a Brainrot and cannot be changed. The only way to get a specific ability on a specific species is to catch more of that species and check each one’s moveset.
Yes. Ability damage and healing scale with the Brainrot’s level. The same move deals more damage on a Level 40 Brainrot than a Level 10 one, even though the ability itself is the same.
Whirlpool at 6 Energy is the highest single-hit damage move in the game. Shield at 2 Energy is the most universally useful defensive move. Grow a Garden at 5 Energy is arguably the strongest in casual play since it both damages the enemy and heals you simultaneously, though its energy cost makes it less efficient in optimized builds.
Epic is currently the highest confirmed rarity tier in the game. Common, Uncommon, Rare, and Epic are the four tiers available as of July 2026.
You need higher-tier Rotboxes. Higher-tier boxes directly improve your catch rate on stronger Brainrots. Upgrade your Rotboxes before entering a new zone, not after you have already arrived and failed multiple attempts.
