Gnarlio is one of the three pests that appeared in "We've Got Pests."
Gnarlio is a light green lizard with a small, slender body. He wears an orange backwards cap, a pink tank top, blue shorts, black shoes with purple laces and black finger gloves. He has dark green eyelids and a long tail.
He likes to look cool, and acts obnoxiously towards others. He looks up to Enid for being cool, and ends up taking her advice to heart. He usually hangs around the Plaza with his friends and trying to pull off cool moves.
He appears in a flash-forward, in which he decided to take life more seriously, getting married to Mrs. Gnarlio, and having a son, he looks back at a picture of Enid and thanks her for helping him figure out life.
