Hoppip is a round, pink Pokémon with long green leaves growing on top of its head. The leaves on its head have ragged edges, similar to a dandelion. It has big, triangular ears with dark insides and beady yellow eyes that lack pupils. Its arms and legs are stubby, and it has a short tail with a rounded tip.
Hoppip's body is very light, and it is easily lifted off the ground by winds and will drift in the air. Hoppip can sense approaching strong winds. In order to avoid being blown away, it clusters and links leaves with other Hoppip or grips the ground firmly with its feet. However, it enjoys gentle breezes. Hoppip lives in grasslands, although some also drift through fields, mountains, and even urban environments.
