Hairyette is a scorpion-like monster student at The Monster Academy. She is often seen with Horrifica and Dizzle, suggesting that the three of them are a close group. Hairyette goes by "Hairy," and is even listed by that name on The Gromble's class ranking chart. She could arguably be considered the third most prominent female character, after Oblina and Dizzle.
Hairyette has a long, segmented, peach-colored body, and blue lips with protruding front teeth and snake-like fangs. She has two eyes with heavy eyelashes, six arms with four digits per hand and two legs. Hairyette wears a purple skirt and black pumps. In Slumber Scare it's shown that she can separate her body segments, each of which can grow bat-like wings—excluding the segment with her legs.
