Bumbo is a passive item added in The Binding of Isaac: Afterbirth.

Effect

• Spawns a familiar which follows Isaac and picks up any nearby coins. Bumbo changes level based on the amount of coins it's collected.

Level 1 (0-5 coins): Bumbo just collects coins to level up.

Level 2 (6-11 coins): Bumbo occasionally drops a pickup, trinket, chest or pedestal item after a room clear.

Level 3 (12-23 coins): Bumbo now fires tears that deal 3.5 damage in the same direction Isaac does. Bumbo's tears have a chance to drop a coin if they hit an enemy.

Level 4 (24+ coins): Bumbo no longer fires tears and instead chases enemies slowly and deals contact damage (2.5 per tick, or 37.5 per second/10.7 per second). Bumbo will occasionally drop Bombs while chasing enemies or coins.

• After reaching level 4, Bumbo will continue to collect coins, and can drop a pickup, trinket, or chest for each coin it collects, similar to Bum Friend.
  • Bumbo can also drop pedestal items.

Notes

• Level 1-3 Bumbo can fly over pits and obstacles, despite having limbs at level 2 and 3 that serve him as legs.
• If Bumbo consumes an absurd amount of coins while level four, Bumbo can become level one again (Unsure if bug, likely a buffer overflow)
• If Level 4 Bumbo targets Mega Satan's head, Bumbo will attempt to "chase" him the entire fight by standing in the middle of the room.
• Level 4 Bumbo's bombs are unaffected by Isaac's bomb synergies.
• Bumbo cannot pick up Sticky Nickels and will hover over them. Level 4 Bumbo can eventually bomb the Sticky Nickel to free it.
• Bumbo will pick up Lucky Pennies, without additional benefit to evolution or drops.
• If Bumbo drops a pedestal item, it will be pulled from the current room's item pool.
• In a RERUN, Bumbo's level is reset.
• Level 4 Bumbo can target charmed enemies and will try to follow them around to no effect. This prevents him from picking up coins until the target is changed.
• There is a similar boss named Bumbino.
• From a scoring perspective, Coins that Bumbo picks up count towards your Schwag bonus on daily runs. (only applies to Afterbirth and Afterbirth ✞ dailies)

Synergies

• BFFS!: Doubles both the contact and shot damage, when applicable.

Interactions

• Box of Friends: Will spawn a level 1 Bumbo regardless of the original Bumbo's current level.
• Bum Friend: The bum friend will follow Bumbo instead of Isaac.
• Keeper: Not recommended, as the coins Bumbo collects could have been used to heal Keeper.
• Tainted Keeper: Due to the large influx of coins spawned, it's technically possible to sustain Bumbo while also maintaining a good level of wealth and health.

Trivia

• Bumbo is the main character of his own game, The Legend of Bum-Bo, designed by Edmund McMillen.
• The name is a play on the word bum and Rambo.
• Bumbo Level 1 looks similar to Bum Friend's head.

Bugs

Bug!	Bumbo's level can be reset after the sequence of obtaining Knife Piece 2 in Ashpit/Mines II.

Bug!	Collision between Bumbo and other bum familiars such as Dark Bum can prevent them from collecting pickups if you're holding one of the firing buttons upon entering a room
