Grotle is a quadrupedal Pokémon with light green skin and a large shell covering its back. The shell is composed of hardened soil and conforms to the shape of Grotle's body, extending from its forehead to the tip of its short tail. The shell appears sectioned and is yellow with three long, brown ridges atop it. There are two bush-like trees growing around the outermost ridges. Grotle's lower jaw is yellow and has triangular extensions on the cheeks, while its upper jaw has a hooked tip. Its feet are yellow and have three claws each. (Source: Bulbagarden.net, CC BY-NC-SA)
