Butch

Butch is the player's go-to for two of the most important meta-progression systems: item storage expansion and Class Collar unlocks. Present on the map from the tutorial onward, he accepts cats that have gone on adventures — and his appetite grows with each upgrade tier, demanding cats that have ventured progressively further. Leveling him up increases your item storage capacity, letting you stockpile more gear between runs and build up stronger inventories over time. He's also the gateway to new classes: after beating an area for the first time, talking to Butch will award the corresponding Class Collar, making him worth visiting after every major milestone. Prioritize his upgrades early — extra storage is one of the highest-value investments you can make in the long run.
