When the Big Red Car breaks down on the way to the studio, Jeff, Murray, Greg, and Anthony have to get out and push. Meanwhile, Captain Feathersword finds leading the preparations for broadcast at the television studio unduly difficult, and most perplexing. After a truly wacky day, the Gremlins are discovered and the Wiggles' world returns to "normal."
