Two friends, a blue jay named Mordecai and a brown raccoon named Rigby, work as groundskeepers at a park and spend their days trying to entertain themselves by any means, much to the chagrin of Benson, a high-tempered gumball machine, and Skips, a pants-wearing yeti but to the delight of Pops, a naïve gentleman with a lollipop-shaped head. Muscle Man, an overweight and green man who frequently removes his shirt, and High-Five Ghost, a ghost with a hand extending from the top of his head, are both neutral about Rigby and Mordecai's shenanigans.
