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 brownish tan 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.
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.
This Pokémon was revealed along with six other Pokémon in July's issue of CoroCoro on June 11, 2010.
No other Pokémon shares the same type combination as Sandile apart from its evolutions.
Sandile and its two evolutionary forms are the second Pokémon family based on a crocodile; the first being Totodile and its evolutionaryforms.
Sandile is based on a baby crocodile. Perhaps more specifically, a Nile crocodile or a literal interpretation of the mugger crocodile, an actual species of crocodile.
Sandile's name comes from the words "sand" (since it lives in sandy deserts and is colored like it) and the last four letters in "crocodile".
Sandile's Japanese name may be a combination of 目 me (eye), 黑 guro (black), and 子 ko (child), due to it being black-eyed.
