Rigby must pass Phys Ed to complete his final requirement for graduation, but arch nemesis, Francis Jablonski does not make it easy for him.
Tropes include:
- The Bus Came Back: Jablonski returns after his previous appearance in The Movie, as a substitute teacher.
- The Big Race: Rigby and Jablonksi have a takeout food race to decide whether or not Rigby passes gym class.
