(in Afterbirth † and Repentance)

Upon getting three items or pills that increase Isaac's size, he will create dust clouds when walking and have a chance to spawn rock waves around him upon taking damage.

(in Repentance) Isaac can also crush rocks and other destructible obstacles by walking over them. Touching spiked rocks sometimes doesn't deal damage, depending on Isaac's size, speed and angle they're touched from.

Notes[ | ]

  • While the Collectible Thunder Thighs iconThunder Thighs item does not contribute to the StompyStompy transformation, it still grants the ability to crush rocks and other destructible obstacles.
  • Picking up items that decrease size do not count against progress for this transformation.
  • (except in Repentance) This transformation makes it more difficult to effectively use Blood Donation MachineBlood Donation Machines and Devil BeggarDevil Beggars, as the rock waves will destroy them.

Trivia[ | ]

  • This transformation and AdultAdult 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.
