The Joke's on Blue

An endless series of practical jokes are being played on the students of Angel Grove High. Bulk & Skull compete against a pair of rival private eyes in tracking down the culprit. Meanwhile, Rito & Goldar are kicked out of the lunar winnebago, and soon bear witness to the return of Prince Gasket, the eldest son of King Mondo, and his wife Archerina. The couple has returned to the Machine Empire after an estranged absence, planning to rid the kingdom of usurper Louie Kaboom. Archerina's love-spell arrow sends Louie on a kamikaze mission against the Zeo Rangers.
