Orson is a tiny chimpanzee from the Mesozoic Era, relative of Slafer and Vikki, and founder of the Wilderness Explorers! He is first found at the very end of part 2 in Journey to the Slafe Slafeceous with Brachiosaurus before getting attacked by King Allosaurus. After the encounter, he returned with Slafer to the present, where Slafer figured out who Orson was. Due to the quantum configurations, he and the dinos all shrunk down. Slafer was glorified at the prospect of meeting the founder of the Wilderness Explorers.
