Catch a Brainrot on Roblox throws you into a creature-collecting loop that escalates fast. The Grass Zone starter brainrots are forgiving enough to grab with basic boxes, but push into the Ice Zone and you will need a serious upgrade in both gear and strategy. With 29+ brainrots currently confirmed across two regions, knowing what you are hunting before you step into a new area makes a real difference.
What are the rarity tiers in Catch a Brainrot?
Every brainrot falls into one of four rarity tiers: Common, Uncommon, Rare, and Epic. Epic is currently the highest rarity in the game. Rarity tells you roughly how hard a brainrot is to battle and catch, but individual creature levels matter just as much. A low-level Epic can still be manageable; a high-level Rare can wall you if your team is not ready.

Where do you find each brainrot by region?
Catch a Brainrot splits its creatures across distinct zones rather than scattering them randomly. Each zone has an early and late section, and the late sections are locked behind secret keys hidden across the map. Finding those keys is not optional if you want the best creatures in each area.
Grass Zone brainrots
The Grass Zone is where every run begins. You claim your first brainrot from the Lab, then head out into this starter region. All 20 of the brainrots listed here are catchable here, including every Epic currently confirmed in the game:
- Glorbo Fruttodrillo
- Capyberelli Bananalelli
- Pussini Sushini
- Trippi Troppi
- Salt
- Ballerina Cappuccina
- TaTaTa Sahur
- Avocadini Guffo
- Rhino Tosterino
- Pepper Shaker
- Zibra Zubra
- Perchello Lemonchello
- Cappuccino Assassino
- Flamingulli
- Tric Trac Barabum
- Chicleteira Bicicleteira
- Spijuniro Golubiro
- Orangutini Ananaini
- Ecco Cavallo Virtuoso
- Bombombini Gussini
Ice Zone brainrots
The Ice Zone unlocks after you have made enough progress in the Grass Zone. The creatures here skew toward the rarer end, with two Epics among the nine available:
- Penguino Cocosino
- Quivioli Ameleonni
- Six Seven
- Svinino Bombondino
- Frigo Camelo
- Brr Es Teh Patipum
- Lirili Larila
- Elephantuchi Bananuchi
- Strawberrelli Flamingelli
Which brainrots should you prioritize?
After testing teams across both zones, the Epic-tier brainrots consistently pull more weight in battles than anything below them. Chicleteira Bicicleteira, Bombombini Gussini, and Ecco Cavallo Virtuoso are all Grass Zone targets worth investing better boxes in early. For the Ice Zone, Strawberrelli Flamingelli and Lirili Larila are the two Epics to focus on once you arrive.
That said, a team of well-leveled Rares will outperform a team of under-leveled Epics. Cappuccino Assassino, Ballerina Cappuccina, and Rhino Tosterino are all Rare-tier creatures that hold up well through the mid-game without demanding the best boxes.
How do Rotboxes affect catching rarer brainrots?
The game uses a box system called Rotboxes to determine your catch success. Higher-tier Rotboxes are required for Rare and Epic brainrots, especially in the late sections of each zone. Heading into the Ice Zone with starter-tier boxes will leave you bouncing off the harder encounters repeatedly. Upgrade your Rotboxes before moving zones, not after you have already arrived and failed a few catches.
