The night before the family leaves on vacation to Club Mellowstar, George shows Elroy some old tools his great-great grandfather used to work with. After they get there, the supervising robot restricts Astro from joining them as dogs aren't allowed at the resort. Elroy later frees him from confinement and the two scramble to get away from the supervisor, only to wind up in an unusual junk land occupied by old obsolete tool robots. Elroy and Astro work alongside some of them to prove they're not as useless as they're regarded. Will the two be able to find a way out of the junk land? (thetvdb.com)
