Mr. Olson is the evil owner of a store at a mall. He appears in "The Tale of the Pinball Wizard". He was portrayed by A.J. Henderson.
He ends up trapping Ross inside the pinball machine as punishment for breaking his trust. How he is able to do this is completely unexplained
Some possible theories could be that, either he is a secretly a warlock or a slightly magical person who creates pinball machines as evil containment units and decides who to put into them.
