After getting a package from Aisha containing a strange golden key and a map of Mysterio Island, the last known location of her long-lost parents, Tanya goes on a quest to reunite with her mother and father. But Louie Kaboom has beaten her to them, leaving the Sloans to perish in the dangerous island caves, after swiping their goal, the legendary Tiki of Auric. Jason, entrusted with the key by Tanya, loses it to Louie, who uses the item to unlock the tiki, unleashing the mighty Auric the Conquerer. He fails to persuade the Zord-sized do-gooding warrior to destroy the Earth for him, so it's up to Prince Sprocket to trick the naive Auric into believing the Zeo Rangers are evil. Meanwhile, despite getting his last one crushed under the foot of a monster, Det. Stone entrusts Bulk & Skull with his newest car.
