Scooby-Doo! Moon Monster Madness

Plot

Daphne attempts to pass her driver's test and obtain her license while driving the Mystery Machine. Velma encourages her, but Daphne crashes the van into a tree and fails. Later, Daphne and Velma win a lottery that takes people into space. At the launch site in Florida, they join billionaire Sly Baron, trained astronaut Shannon Lucas, retired astronauts Zip Elvin and Colt Steelcase, alien hunting specialist Ridley, football player Uvininous "U-boat" Botango, news reporter Clark Sparkman, and Fred, Shaggy, and Scooby-Doo.

Fred allies himself with Zip and Colt, to their dismay. Shaggy and Scooby are happy to see U-boat. Shannon informs Daphne that she scored highest on the space test, surprising Velma. Velma grows irritated with Daphne.

Everyone boards Sly's ship, the Sly Star One, and blasts into space. They meet a robot named H.A.M. with a horrible, dark sense of humor. A mysterious alien disrupts the ship, forcing it to land on Sly's space resort on the dark side of the Moon. They are greeted by Sly's twin brother Hudson and Sly Bots.

Scooby and Shaggy search for food while the others seek the alien. Velma's bitterness toward Daphne increases, straining their friendship. Fred continues to annoy Zip and Colt. Scooby and Shaggy are briefly chased by the alien and meet U-boat, who advises thinking of something un-scary when frightened.

Fred devises a plan to trap the alien. During the trap, Daphne and Velma confront each other, and Velma wonders what remains for her if Daphne is the astronaut.
