S04E40 - Where in the World is Zeo Ranger 5?
Synopsis
Determined to prove that he can take control of the Machine Empire in his father's place, Prince Gasket captures Tommy while he's out testing his uncle's prototype waverunner. The now-leaderless Rangers are oblivious to his fate, and their attempts to track him are hindered by the Cruel Chrome monster, created from Det. Stone's own waverunner (which Bulk & Skull were attempting to wash for him). Meanwhile, the lunar winnebago gets its booster rocket repaired by Rito & Goldar, with uncontrollable results.
