Bumbo is a familiar in The Binding of Isaac, added in the Afterbirth DLC.

Spawns a familiar that follows Isaac and picks up nearby coins. The familiar changes level and behavior based on the number of collected coins.
• Level 1 (0-5 coins): only collects coins to level up.
• Level 2 (6-11 coins): has a chance to drop a random pickup, trinket, chest or pedestal item after clearing a room.
• Level 3 (12-23 coins): fires tears in the same direction as Isaac that deal 3.5 damage and have a chance to drop a coin if they hit an enemy. The familiar shoots 1.36 times per second.
• Level 4 (24+ coins): no longer fires tears and instead chases enemies, dealing 2.5 damage per tick (10.71 per second). Will occasionally drop bombs while chasing enemies or coins. Has a chance to drop a pickup or item after each coin collected.
