Turtwig (Japanese: ナエトル Naetle) is a Grass-type Pokémon. It evolves into Grotle starting at level 18, which evolves into Torterra starting at level 32.
Along with Chimchar and Piplup, Turtwig is one of three starter Pokémon of Sinnoh available at the beginning of Pokémon Diamond, Pearl, and Platinum.
Turtwig's appearance is characteristic of a turtle or tortoise, and it is primarily light green in coloration. Its prominent, yellow-colored jawbone may denote a relationship to the snapping turtle. Its green and yellow body is covered by a shell. A small seedling grows on a brown-colored patch on its head, similar to the plant bulb on Bulbasaur's back and the leaf on Chikorita's head, the plant part revealing its Grass-type nature. The brown shell on its back has a thick black stripe and rim, and is apparently made of earth. The shell should feel moist on a healthy Turtwig. Turtwig’s eyes are yellow, as are its feet, and Turtwig’s tail is small.
