The Character(s): “Ooooooh!”

Officially known as the Squeeze Toy Aliens, these three-eyed, three-fingered intergalactic residents of the claw machine arcade game were originally going to be plastic pizza prizes.

Somewhere along the way they morphed into these adorable critters. They're forever searching for a leader.

Screen-time: The little green men make sporadic appearances throughout both Toy Story movies.
 
Lasting Impression: They were so well-received in the first Toy Story that they cropped up again in the second. They’ll go for gold with a third appearance in the new sequel.
