Completing this transformation will take the three bums and replace them with the Super Bum familiar, who automatically collects all coins, red hearts, and keys in the room and drops twice as many rewards as the regular bums would have produced.

Notes

  • This transformation has a unique animation sequence when the third bum is picked up.
  • When Dark Bum is obtained through Collectible Cambion Conception icon.png Cambion Conception, it does not count towards the transformation.
  • If multiple bums of the same kind were present before the transformation, e.g. via Collectible Box of Friends icon.png Box of Friends, all of them will be replaced with only one Super Bum when three different bums are obtained.
  • If any additional bums are obtained after the transformation, they will not be displayed on the screen.

Trivia
