Origin and inspiration
Skiddo is inspired by a goat kid. it seems to be based on a bike with its ability to be ridden and its horns being like a bike's handlebar. Its grass fur may be based on Pan and other gods of nature that are half-goat, or the yule goat figures in northern Europe.
Skiddo may be a combination of skid and kiddo, but its anime pronunciation implies it is a corruption of Ski-Doo, a brand of snowmobiles.
