- His posthumous version is The Bloat.
- He has 3 unused sprites in his spritesheet that were removed in The Bloat spritesheet.
Bugs[]

Peep's Eyes have the same collision radius as Peep itself, which results in the eyes being difficult to dodge since the hitbox doesn't match up with the eyes' visual size. |
