This is a story about the adventures of two 23-year-old troublemaker friends - a blue jay named Mordecai and a raccoon named Rigby. The main characters work as park keepers, and they spend their days slacking off and coming up with various entertainments. These guys can't spend a single second without doing something, which sometimes leads to unpredictable (and surreal) consequences. They often have to explain themselves to their boss Benson (a living gumball machine), but with the help of the wise yeti Skips, they manage to solve almost all difficulties.
