Lab Rat Lift-Off / Rockin' Rockhound Polaris the Astro Cat, who Ginny is a big fan of, is going on a trip to the Moon. Thinking that the Moon is made of cheese, Lab Rat plans to get into the rocket instead of Polaris in order to get to the Moon. After Lab Rat and Otto trap Polaris in a truck, the SuperKitties rescue her and work with her to thwart Lab Rat. The SuperKitties are called in by Magda to help guard the Sky Jewel which was found by her nephew Rockland Rockhound and is on display on the museum. Despite Sparks' security system, the Sky Jewel is stolen by Zsa Zsa and her Budgies in order to replace her lost cameo broach.
