Wiggler

Wiggler is a caterpiller-like creature from the Mario series that made its first debut in Super Mario World. If Mario jumped on it, it would get mad and start running around faster. There was no way to kill it unless Mario had Yoshi whom could eat it, were carrying a Koopa Shell, or had the powers of a Starman.

Most Wigglers have 5 little sections in there bodies that are in the shape of a sphere, though many have more, including one that is in New Super Mario Bros. that has up to 100 (Not confirmed, but likely.)

Though most Wigglers are enemies, they just usually get mad if you harm them first, other than that, they always look happy, and will also be friends with Mario in some games.

Trophy Description
''A large caterpillar characterized by a flower on its head and a huge nose. Wigglers typically just walk around minding their own business, with no hint of malice. However, they lose their flowers when jumped upon and fly into a rage, turning bright red and chasing Mario. In Yoshi's Island, certain Wigglers appear as butterflies, with grown wings and flight capabilities.''
 * Super Mario World, 1991
