Jigglypuff

A round balloon Pokemon. Jigglypuff lures in enemies with it's round, cute eyes, and puts them to sleep with it's soothing song. When it's angry, it puffs up into an abnormally large size. It's body is fairly elastic. Jigglypuff evolves into a Wigglytuff when exposed to a Moon Stone. When two Jigglypuffs or Wigglytuffs breed, they result in an Igglybuff. That makes the Evolution Chain:
Igglybuff > Jigglypuff > Wigglytuff
Jigglypuff is a Normal-Type Pokemon, and usually isn't the best choice, even as Wigglytuff.
Jigglypuff's Japanese name is Purin, and it has a huge fanbase there. Enough to have it as a character in Super Smash Brothers.
