They are a cross between an amphibian (frog) and a monkey, with a horn. They are described as being hairless, with smooth, mottled green skin, and webbed hands and feet, and long limbs that are good for climbing and swinging.

Clabberts are native to the Southern United States, live in trees and feed mostly on lizards and small birds. They possess a pustule in the middle of their forehead that glows red and flashes in the presence of danger.
