Notes:Wollyhop/olimar

It is believed that juvenile wollywogs were once carried by underground current into caverns, where they thrived in the dark habitat. This troglodytic species of wollywog's coloration results from generations of cave dwelling and lack of sunlight. Comparative differences between the size and shape of this wollywog and other species are thought to be the result of natural selection at work, choosing traits better suited to life in a subterranean environment.
