They pursue it to the Babies and Toddlers: Outdoor section, where they see the Little Green Men being picked up by a retractable hook on the flying saucer. Sora and his friends defeat it, removing the darkness that possessed it. The Little Green Men, now safe, say that "Nirvana will not be reached," but also say that they have their new home, Andy's room.

Origin
The Little Green Men first appeared in 1995, in Pixar's first feature film Toy Story as prizes from a claw game, one of whom was won by Sid Phillips and given to his dog Scud as a chew toy.

The three who appear in the game debuted in Toy Story 2, where they were first hanging from a mirror in a Pizza Planet trucked hijacked by Buzz Lightyear to chase after Al, who was taking Woody to Japan. After Mr. Potato Head saved them from falling out of a window, they joined the rest of Andy's toys, and were adopted by Mrs. Potato Head.
