The Peroro (ペロロ) is an enemy that appears in Sonic Labyrinth, encountered in the Labyrinth of the Castle.
They are tiny bots with blue bodies that roll slowly along the ground on their wheels, pausing occasionally to unfurl their ample tongues in a similar fashion to frogs or chameleons. Their name is derived from "pero-pero", which is a Japanese onomatopoeia meaning "to lick".
