Wigglers seem to transform into Flutters immediately (or temporarily, in some cases such as Mario Power Tennis) without going through a cocoon stage as typical real-world caterpillars do. In Super Mario World 2: Yoshi's Island, a fully grown Wiggler variant known as a Flutter makes an appearance, confirming that Wigglers are indeed caterpillars.

Wigglers appear usually as enemies, but some are allies and even playable. Wigglers in all appearances are easily identifiable by the characteristic flower or other plant growing from their heads, which can lose their petals if Wigglers are enraged. Wigglers are a species resembling caterpillars that first appear in Super Mario World, where they are yellow and slowly moving when calm, but turn red and run angrily about quickly if jumped on.
