What Stompy does
- Allows Isaac to crush rocks and other destructible obstacles by walking over them.
- Taking damage has a chance to create damaging rock waves around Isaac.
- Adds dust clouds while walking as a cosmetic effect.
How to transform
Build 3 size-up counts from Magic Mushroom, Leo, and repeated One Makes You Larger pills.
Each use adds one size-up count toward Stompy.
Qualifying pickups
Every item that counts
Rules that matter
Keep these exceptions in mind
- One Makes You Larger can be used repeatedly for multiple counts. Size-down effects do not remove progress.
