Notes[]

  • Picking up items that decrease size do not count against progress for this transformation.
  • This transformation makes it more difficult to effectively use blood donation machines and Devil beggars, as the rock waves will destroy them.
    • Added in Repentance The rock waves will no longer destroy them.

Trivia[]

  • This transformation and Adult are the only transformations that pills count towards.
  • This is the only transformation that doesn't add to Isaac's costume, and instead only changes his size and adds dust trails when he walks, as if kicking up dirt by stomping.
