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.
