Wiggler
Wiggler (Japanese: Hanachan) is the caterpillar-like creature in the Mario series of games. It made its first appearance in Super Mario World, where it first displayed its trademark characteristic of becoming red and enraged when jumped on by Mario, Luigi, or Yoshi. It usually has a yellow color. When it's calm, it wears a flower on its head. However, when it becomes angry its eyes become enraged, it loses its flower, and it becomes red. Later, it appeared in various other Mario titles, including Super Mario 64, Mario & Luigi: Superstar Saga, and Super Mario 64 DS. Wiggler underwent some major changes in Super Mario Sunshine where it multiplied its size tenfold and turned green.
Wigglers were seen occasionally in the animated series that spun off of the game. However, on the show, they were called "Caterpillars", and were always drawn like they had already been stomped.
