No need to knock, just step right in. You’re just in time to two-step with Grandfather Robinson and his dancing frog band. Cousin Laszlo is demonstrating his new antigravity device. And Uncle Art’s flying saucer is parked out back. It seems like all the Robinson relatives are here, so be prepared. And keep your head down…Uncle Gaston is testing out the family cannon. Oh, and watch where you sit, Grandpa’s lost his teeth again. Welcome to the Robinson’s.
