Sandile largely resembles a crocodile. It has what appears to be a black stripe near its eyes in the appearance of a mask, and is mainly a light tanish brown with black striped through its body. On its belly it can be noted that a pink replaces the tan shade, though the stripes continue regularly. It has four legs, a short tail, and three claws to each foot. Its eyes don't seem to have any sort of coloring besides black, and it has large nostrils. No teeth show when its mouth is closed.
In the anime
Sandile first appeared in A Sandile Gusher of Change, where a group of Sandile were causing trouble at a hot spring resort. However, it later transpired that the Sandile were trying to warn of impending danger and, with the help of Ash and his friends, were able to save the Pokémon in the area. The leader of the gang sports sunglasses, much like Ash's Squirtle, and has since featured in several episodes.
