At a public park staffed by a menagerie of oddball creatures, best friends Mordecai the blue jay and Rigby the raccoon are supposed to be groundskeepers, though they invest most of their energy dodging actual work. Their attempts to slack off and cure their boredom routinely spiral into cosmic catastrophe, dragging in their uptight gumball-machine boss, a hulking yeti foreman, and a lollipop-headed manager. What begins as a mundane workday reliably escalates into battles with time-traveling villains, vengeful arcade ghosts, or the fate of the universe itself. Wrapping surreal, high-concept absurdity in an easygoing 1980s sensibility, the animated comedy finds heartfelt friendship at the center of its gleeful chaos.
