Fright Height has the appearance of a goblin. His body is a mix of orange and black; the majority of his skin is orange, save for two bands around his wrists, a stripe going down the middle of his face and chest, torn shorts going to his knees, and bands around his ankles being black. He has a set of withered wings connecting to his arms and his back, which are also orange. He has pointed ears and five clawed fingers; he also has two clawed toes.
Primarily from his mouth, the acid is built up inside of him. He has an extra organ that creates the acid and it doesn't interfere with his bodily functions.
