Cat-Stro-Bot has been with the CatStronauts through it all. But now he's stranded on Jupiter's coldest moon after a mission gone wrong--and his best friend/creator Blanket isn't about to leave him behind.

When CATSUP refuses Blanket's rescue mission request, he creates robo-stand-ins for the team so they can sneak off into space. Soon, the rest of the CatStronauts, Major Meowser, Pom Pom and Waffles, are off on their longest journey ever with experimental new technology. The robot rescue is afoot!
