The kilted stimpy is the smallest stimpy species known, weighing only 5 kg. They are also the only stimpies known to jump between trees ---other stimpies prefer to climb down if they cant travel between trees by walking from branch to branch. This may also explain the peculiar hairy "skirt" or "kilt" after which this stimpy has been named. The elongated hairs on their arms and rear legs may help the kilted stimpies to extend their jumps further, as in the stiff plumage of a pithecosaur.
