Otto von Goon is sheriff Schulz Meisterson's right hand/helper/pet Goon. He is smarter than the other goons because the sheriff has trained him many things (for example the sheriff trained him not to kill everyone who is bad, but to only break a few bones).
Otto is seen next to the sheriff during day, playing with a yo-yo. He sleeps downstairs in the sheriff's house at night, as seen by the thief when he goes to rob the sheriffs house. Otto sometimes nightwalks and also passes through a door without opening it. Also, he kills the thief if he is not careful enough.
