Scooby-Doo! and the Alien Invaders
The gang are on (once again) the road, when Shaggy and Scooby drive (how did that happen) but the car brakes as a flying alien ship goes above them, so they have to go to a near-by city named Roswell as Shaggy and Scoob go screaming saying they saw aliens, a strange guy Lester confirms he's seen them too, so he's taking the gang to his house, to show them pictures, when it turns out he was talking about drawn pictures (not taken with a camera, get it?), but they stay there through the night, when Shaggy and Scooby get captured by the aliens and wake up in a middle... of nowhere. There a very beautiful and smart girl called Crystal and her dog Amber help the guys out as they fell in for each other, but the mystery is still going! The gang also meet some suspicious UFO scientists and a mechanic, that turns out to be an FBI agent. At the end, Crystal and her dog are revealed as the real aliens and friends helping the gang getting the three scientists masked as aliens that had in mind to steal the gold while scaring off everyone who would come!
