Krokorok

Krokorok (Japanese: ワルビル Waruvile) is a /-type Pokémon that was first introduced in the Generation V games Pokemon Black and White. Krokorok is the evolved form of Sandile, and the pre-evolution of Krookodile. It evolves at level 40. It is used by Leader Clay.

Appearance
It is similar in many ways to its pre-evolution. It has the same shade of tan and a pink belly, with black striping showing through constantly. It now walks on two legs rather than four. Its tail is longer, and there are spikes along the spine of Krokorok. The nostrils are more proportioned to the rest of the face than its pre-evolution, and the hind claws are now white. The claws are still three for each leg, and the teeth show even when the mouth is closed. The arms are less muscular now, presumably due to walking on only the back legs. It resembles a T. Rex with the tiny arms and large back legs

In The Anime
Krokorok first appeared in BW020: Dancing With the Ducklett Trio after the Sunglasses Sandile, appearing in BW003, and BW012 evolved into Sunglasses Krokorok during a battle with Ash's Pikachu

Evolution
Krokorok is the evolved form of Sandile as of level 29. Krokorok evolves into Krookodile at level 40

Trivia

 * Krokorok's design appears to be based on both that of a Crocodile and a Tyranosaurus Rex.
 * No other Pokémon shares the same type combination as Krokorok and its evolutionary relatives. As a result, they are the only Pokémon to recieve STAB from the famous Earthquake-Crunch attack combination.
 * Krokorok was first revealed in the United States (along with many other non-released Pokémon) through pictures leaked onto Serebii.net by Japanese players who recieved their copies of Black and White early.
