Rot Box Tiers

Rot Boxes determine which rarity of Brainrot you can catch. Higher-tier boxes unlock the ability to capture rarer species. Duplicate catches give 5x more coins than defeating.

100 Coins|Common → Uncommon

Your starting Rot Box. Best for catching Common and Uncommon Brainrots in Rot Forest. Upgrade early to improve catch rates.

Advanced Rot Box

500 Coins|Common → Rare

Improved catch rates for Rare Brainrots. A solid mid-game investment before heading to the Snow Forest zones.

Premium Rot Box

2,500 Coins|Common → Epic

Essential for hunting Epic-tier Brainrots. Increases your chance of capturing Glorbo Fruttodrillo, Flamingulli, and Bombombini Gussini.

Ultra Rot Box

10,000 Coins|Common → Insane

The ultimate Rot Box. Required to have any realistic chance of catching Insane-rarity Brainrots like Torrtuginni Dragonfrutinni and Graipussi Medussi.
