Willy’s class will blast off for the afternoon, learn about outer space, and be home in time for dinner. But when he wanders off on his own, Willy ends up being left behind on Ed! Can Willy, along with his classmate Cindy and an alien boy named Norp, outsmart the big hungry monsters on Ed until someone rescues them? With a little help from an android who likes knock-knock jokes and a seagull with terrific aim, they just might!
