Slimer is playing with a toy spaceship, when a real spaceship grabs it with a tractor beam. Slimer tries to grab it back, when he gets pulled up too, and lands in a chair. Robot arms strap a seatbelt on him and give him food, and a voice says he's won a vacation.
The aliens driving the spaceship watch Slimer through a viewscreen, and one of them finds him ugly but the other finds him cute. The one who called Slimer ugly says that he's their "enemy" and that they will determine his weaknesses and use that knowledge to conquer Earth.
Slimer then tries to play with his toy spaceship instead, but the remote ends up controlling the actual spaceship instead. The grumpy alien thinks Slimer's remote control is a "secret weapon" and uses the robot arm to steal it. Then, they dump him in a building on another planet, where he tries to escape from but can't.
The aliens put Slimer in a spinning machine to see if it's his weakness, but he enjoys it, then the machine goes out of control and breaks. Then, the aliens try seeing which weathers Slimer is weak to, but when they make snow he just finds it fun, and when they make wind he initially gets blown away but then he not only learns to resist it, he flies a kite. They try extreme heat, but he enjoys that too, so they turn the heat up, but he roasts sausages over the fire.
Slimer then blows up half the planet, but the aliens survive and take him back.
