Unlike the cowardly Ickis, and the smart Oblina, Krumm is rather shy. He is quite an interesting monster. He can juggle his eyeballs, and relies on his body odor as part of his scare strategy! Despite his strange appearance, Krumm is quite soft-spoken, and is actually quite shy. This hasn't stopped him from starring in a movie or from contaminating a vat of perfume with his putrid stench. Krumm is always up for an adventure, and never fails to keep an eyeball out for his friends!
Krumm is an orange-tan color. He has a big nose and two arms. His eyes are white with black pupils and rather than being set in his head or body, are held by Krumm in his upstretched hands. Occasionally, he holds both eyes in one hand. Krumm has blue lips and two short legs. He has black-colored armpit hair (that occasionally appears as gray-coloured) and five toes on each of his two feet.
