A spaceship lands next to the Wiggles' house, and when Greg, Murray, Jeff and Anthony hop aboard to explore it, they find themselves lost in space after Captain Feathersword accidentally launches them. Their destination? The planet Rock Star, where King Mondo awaits them, dancing the "eagle rock." Can they get back to Earth? Music holds the key to their return. Also includes a "Return to Earth" game, a behind-the-scenes look and more.
