Scooby-Doo! Moon Monster Madness

Daphne attempts to pass her driver's test aboard the Mystery Machine and crashes into a tree, ending the attempt in failure. Velma offers encouragement but the setback strains their confidence. Soon after, Daphne and Velma win a lottery that will take them and friends into space.

Daphne and Velma learn that the lottery will launch them into space with a diverse crew. They prepare for an adventure that will push them beyond Earth. The mission promises excitement and danger in equal measure.

The gang boards Sly Star One and blasts off into space, leaving Earth behind. Fred aligns himself with Zip and Colt, while Sly Baron, Shannon Lucas, Ridley, U-boat, and others join the voyage. The ship hums with anticipation as the crew heads toward the stars.

In space, the crew meets H.A.M., a robot whose humor is dark and off-putting. H.A.M.'s snark both amuses and unnerves the team as they settle into life aboard the ship. Tensions hint at the trouble ahead.

An unseen alien starts messing with the ship, forcing a crash landing on Sly's space resort on the Moon's dark side. The crew must face an unfamiliar threat far from Earth as the resort comes to life around them.

Sly's twin Hudson and a fleet of Sly Bots greet the travelers at the resort. The unknown host is warm but the situation remains tense as plans form to confront the alien. The group begins to explore the resort while keeping an eye on trouble.

Scooby and Shaggy head off for food, while Fred, Velma, and the others search for the alien. Velma's growing bitterness toward Daphne thickens, creating a rift in their friendship. The atmosphere becomes strained as trust wavers.

Uvininous 'U-boat' Botango reassures the crew—especially Scooby and Shaggy—by suggesting they focus on something not scary when fear spikes. The advice brings a brief pause to the mounting tension. Still, the danger remains.

Fred orchestrates a plan to trap the alien, using his newfound acceptance from Zip and Colt. The group closes in on the creature, while Daphne and Velma continue to clash over the astronaut future. The crew presses forward despite the interpersonal strain.

Shannon is revealed to be behind the alien disguise. She admits she wanted to scare Earth away from civilian space travel and tries to manipulate the team. The revelation shatters several friendships and escalates the stakes.

Shannon traps the heroes behind a glass wall and plants explosives around the resort to blow it up. She returns to the now-repaired Sly Star One and escapes to Earth alone, leaving the others to face certain danger. The group scrambles to break free before disaster strikes.

H.A.M. reveals that he is not a robot but a human actor, shifting the group's understanding of the situation. The gang escapes the glass prison and discovers a replica Sly Star One built by Hudson and the Sly Bots. Zip and Colt hold the tank steady while Fred earns their respect.

Velma's faith in Daphne grows as she tells her best friend she can fly them home. Inspired, Daphne takes the helm and powers the ship off the Moon toward Earth. The crew prepares for the long journey home.

Back on Earth, the heroes confront Shannon and expose her scheme, leading to her imprisonment. Daphne and Velma reconcile, realizing their friendship is stronger than their disagreements. Daphne drives the Mystery Machine home with Fred, Shaggy, Scooby, and everyone else.
