"A lovable outcast amongst the other alligators living in the sewers. He enjoys showering which is something the other alligators just don't understand. Unbeknownst to him the other alligators routinely tamper with his plumbing to stop his showers. The player's goal is to get water to Swampy's broken showers so he can indulge in his favorite pastime." - Where's My Water official website
Swampy is an anthropormorphic alligator and the main crook of the Where's My Water? game series.
Unlike other alligators, Swampy is very nice and follows the golden rule. He is in love with Allie, who used to love Swampy's enemy, Cranky. (This attraction was first revealed in "Sink or Swim", when in the beginning cutscene, Swampy finds a bow he wants to give to Allie.) Swampy also hates his Rubber Duck. He likes Poison Water, Ooze and Mud and wants to take a shower with just plain Water.
Swampy takes on the appearance of a anthropomorphic short green alligator that walks on two legs. His eyes have blue irises, and he has three teeth poking out of his mouth; two on the left side, one on the right. He has a long curvy tail with purple rounded spikes running down it and his back. He also has lighter green spots on his arms and legs, a light-green belly, and blue-colored claws on his hands and feet.
