Hoppo

Hoppos are purple hippos with a flower-like pattern on top that first appear in Super Mario Bros. Wonder. They appear prominently in a level with their own name, Here Come the Hoppos. The player can stomp on them to make them start rolling and bounce off of them. Hoppos can also roll into and get stuck in gaps.

During the Wonder Effect in Here Come the Hoppos, the player has to bounce off of rolling Hoppos to reach a big one carrying a Wonder Seed.
