Tropical Wiggler

Tropical Wigglers are a species resembling large real-world caterpillars. They first appear in Super Mario Odyssey, where they are yellow, blue, and red and slowly moving.

Appearance
Tropical Wigglers, different from their initial incarnation in Super Mario World, are depicted as large, yellow, blue, and red caterpillars with large brown noses, with no small flower on their head, wearing shoes. Tropical Wigglers also have orange spots scattered throughout their bodies, and spikes on each section of their body.

History
Mario can take control of a Tropical Wigglers, he will be able to extend himself to a certain length in any direction; however, the front or back segments of his body must always be resting on solid ground, for as soon as Mario reaches his full length, his body will contract, and if he is not standing somewhere firm, he will fall.
