Rob hates Dib. When Dib sat next to him on the bus headed for a wormhole, Rob got up and went to a different seat. Rob gave Dib a wedgie on the same bus. On Halloween, Rob wore a gasmask. Dib once told him that his daddy is a Yeti, and this upset Rob quite a bit. Rob cried about this while being interviewed for Mysterious Mysteries. When the class got lice, Rob banged his head against Sara's head. A monkey later picked lice off of Rob's head. Rob once shared a lollipop with Zooglodon. On Valentine's Day, Ms. Bitters transferred Rob to the 'underground classrooms' to open up a seat for Tak. Rob survived and took his seat back in the second season. In season 2, Rob grows a full head of hair.
