Watch Scooby-Doo! Robot Mystery

When Sheriff Stone confesses to the gang that he was abducted by aliens as a child, Mystery Inc. decides to look into his claims that aliens are now running around Crystal Cove taking high-tech devices (clearly trying to rebuild their crashed spaceship so that they can get off our planet and get back to their inter-galactic war that's happening all around us!) The gang is skeptical at first but circumstances keep leading them to believe the Sheriff. Strange things have been happening lately. Who's to say aliens aren't real? Things get stranger still when the aliens steal Barty Blake's brand new high-tech electric car right out of the Blake mansion. The gang gives chase! Meanwhile, Scooby and Shaggy think they've figured this mystery out. And, with a little sleuthing with Velma, they actually uncover the mystery. Turns out, there are no such things as aliens...well, at least not in this episode!

After a thief breaks into Daphne's room, Scooby discovers that he's got competition in the detective dog division--Robopup, a mechanical wonder dog. While Scooby attempts to compete with the technological marvel, the gang solves the mystery.

Robi goes on the blink during the eve of an all-important mansion housewarming party, forcing Scooby and Shaggy to replace him with a new robot butler. Little do they know, the new "ro-butler" is actually a terminator-like annihilator-bot built by Dr. Phineus Phibes. After Scooby and Shaggy repeatedly frustrate the robot, Dr. Phibes gives the order for a full-on assault. By using a Scooby Snack that gives Scooby transforming battle-bot capabilities - and with the help of Robi, who has been sequestered in a closet- Scooby and Shaggy fight back. In the end, they save themselves from being expelled from the neighborhood; manage to make Mr. Havansimp, the President of the housing association, a foot taller; and, in the meantime, throw the best party in history.

Scooby and Shaggy travel into the desert to discover that Dr. Phineus Phibes has built a giant, weaponized robot in his image. Phibes' plan is to merge with the robot through a "neural connection" and become one with it, thus making himself both all powerful and immortal. Scooby and Shaggy put a big kink in Phibes' plans by accidentally stowing away in the giant robot and ending up at the controls. After chasing Scooby and Shaggy across the desert to Hoover Dam, Phibes ejects them from his robot by overriding the controls and picking them out if its nose with a giant robot finger. When Phibes gets inside his giant robot, Scooby and Shaggy have no chance. That is until Scooby eats a Super Scooby Snack that makes him a giant robot as well. Scooby is victorious in the "bot-vs-bot" battle that follows, and Phibes is once again foiled.

Here, they find the abandoned Missionary town that slid into the sea some 300 years ago. And it's full of killer robots, digging for something.
