Zuruggu

Zuruggu is a bipedal, lizard-like Pokémon. Its oval eyes are set to the sides of its head, and its teeth appear to be constantly exposed. There is a small red scale on its yellow head. Below the yellow portion of its head, its body is cream-colored with thin arms and a red, scaly belly. It carries its loose, yellow skin around its legs, resembling trousers, which garner them more respect the saggier they are. Some of the loose skin seems to trail off to form or cover a tail.

This pelt is rubbery and can be raised to its neck in order to reduce the damage it takes from attacks. The more saggier its skin is, the more respect Zuruggu will earn. Zuruggu is easily engaged in battle, as it will attack any foe that so much as meets its gaze with its thick cranium. Zuruggu are known to be proud of its sturdy skull Zuruggu travel in small groups moving in a lazy fashion. Zuruggu is said to evolve into Zuruzukin once its skin is completely stretched out.
