Don't Call Me Gadget!

Colonel Nozzaire is captured by aliens who think that he is Gadget. They do tests to see if he is Gadget, which he fails. Gadget tries to find him, but when he finds the aliens, he doesn't realize who they are. When the aliens trick Gadget onto boarding their ship, when find out they have a deal with Dr. Claw where they'll exchange Gadget for the moon. One of Claw's agents tells them that Gadget is really dangerous, so the aliens put a device on Gadget that will reverse his brain waves. Thinking that he is really smart, but acting stupid, they put it on him. Gadget ends up being really smart and saves the day by stopping Claw and telling the aliens that no one owns the moon, so they can live there if they want.
