Pufferfish

Pufferfish are enemies encountered in Crash Bandicoot 3: Warped in the underwater levels. If Crash gets hit by one when it is inflated or fails to spin them away when they are deflated, it will blow helium into Crash and he will blow up like a balloon on occasion. Pufferfish also appear in the underwater levels in Crash Bandicoot: The Huge Adventure for the Game Boy Advance and attack in a similar pattern.
