Oddish

It has a round body, beady red eyes, a small mouth, and ovoid feet. Five large, green leaves sprout from its head. As demonstrated in the anime, these leaves are prehensile and can be used to scale vertical surfaces and catch light objects. 

A nocturnal Pokémon, Oddish buries its sensitive body in the ground during the day to avoid the sun and fool predators. If its leaves are pulled in this state, it will respond by shrieking horribly. It starts to move when its leaves begin absorbing moonlight, which it uses to grow.
