Binding of Isaac: Rebirth Wiki

(except in Rebirth)

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.
Bumbo level 1 Level 1 (0-5 coins): Bumbo just collects coins to level up.
Bumbo level 2 Level 2 (6-11 coins): Bumbo occasionally drops a pickup, trinket, chest or pedestal item after a room clear.
Bumbo level 3 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.
Bumbo level 4 Level 4 (24+ coins): Bumbo no longer fires tears and instead chases enemies slowly and deals contact damage (2.5 per tick, or (except in Repentance)37.5 per second/(in Repentance)10.7 per second). Bumbo will occasionally drop BombBombs 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 Collectible Bum Friend iconBum 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 Head ingameMega 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 NickelSticky Nickels and will hover over them. Level 4 Bumbo can eventually bomb the Sticky Nickel to free it.
  • Bumbo will pick up Lucky PennyLucky 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.
  • (in Repentance) There is a similar boss named Boss Bumbino ingameBumbino.
  • 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[ | ]

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

Interactions[ | ]

  • Collectible Box of Friends iconBox of Friends: Will spawn a level 1 Bumbo regardless of the original Bumbo's current level.
  • Collectible Bum Friend iconBum Friend: The bum friend will follow Bumbo instead of Isaac.
  • Character Keeper iconKeeper: Not recommended, as the coins Bumbo collects could have been used to heal Keeper.
  • (in Repentance) Character Tainted Keeper iconTainted 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.

In-game Footage[ | ]
