Puffer fish were a species of small fish that can inflate into a ball shape as a defense mechanism from predators.
Also known as blowfish, these clumsy swimmers fill their elastic stomachs with huge amounts of water (and sometimes air) and blow themselves up to several times their normal size. Some species of puffer fish have spines on their skin. Even if a predator tried to eat a puffer fish, it's meal won't be satisfying. Most pufferfish contain a toxic substance that makes them foul tasting and potentially deadly to other fish and animals.
In Ice Age Village, they play as obstacles in the mini game Kung Fu Scrat. If a players swipes their finger on them three times, instead of slashing a Piranha, they will lose the game. Puffer fish, along with piranhas also appear as obstacles in the mini game Sid's Egg Rescue featuring Sid himself.
