Muppets from Space

Gonzo is contacted by his alien family through his breakfast cereal. But when the men in black kidnap him, it's up to Kermit and the gang to rescue Gonzo and help him reunite with his long-lost family.
When Gonzo's breakfast cereal tells him that he's the descendant of aliens from another planet, his attempts at extraterrestrial communication get him kidnapped by a secret government agency, prompting the Muppets to spring into action. It's hard to believe Gonzo's story at first, but Kermit and friends soon find themselves on an epic journey into outer space filled with plenty of intergalactic misadventures.
