Deep within the inner sanctum of Andy's next-door neighbor, Sid's room, lies a collection of toys that no boy should have created. Where Andy's room is a haven for Woody, Buzz, and all the other toys, Sid's room is no-man's-land -- the work of an unwell mind. Here's all the info you'll ever need on the creation of mutant toys.

Built from the severed torso of Rocky Gibraltar, a wrestling doll, Rockmobile has a bug's head sticking out of his neck instead of a brain of his own. According to Rick Sayre, the man who built Rockmobile, he has the psychotic personality of several different characters. He gets around not on legs, but on the hands of the driver who steers the entire contraption.

Elliot Smyrl, the builder of Babyface, gave a drastic haircut to a baby doll to get the perfect look for this mutant toy. His body is built from an erector set. Babyface only has one eye, but it rotates like all baby doll's eyes do. When he lies down, the eye closes.

Creator Damir Frkovic describes Rollerbob as an air force aviator with a parachute strapped to his back who's been taken apart and cruelly screwed to a skateboard. His only way to get around is by paddling along with his hands.

When Sid's sister tracks down her Janeydoll, something about it is different. That's because Sid replaced the normal doll's head with that of a pterodactyl.

This is another classic toy in the "Toy Story" team -- at least, it was once. Frog, built by Damir Frkovic, is an old windup metal toy missing a front leg, and his two back legs have been torn off and replaced by different kinds of wheels. He moves around like a hot rod. At a key point in the film, Woody delivers the immortal line "Wind the frog!" and the Frog jumps in to be used as a decoy.

Mark Adams took a young child's rolling toy and replaced the stick on top with a GI Joe head. But that wasn't enough. Adams then added a Mr. Potato Head® arm onto his side so that he can move around.

Take a Pez dispenser and cross it with a spring-loaded suction cup toy and you've got the mutant named Duckie. He doesn't talk, but his spring squeaks. According to Graham Walters, the man who built him, the animators of "Toy Story" are fond of having him lean backward and forward on his base. Duckie moves just as you'd imagine he would -- he scrunches down, loads his spring, aims, and leaps forward when it pops.

Mark Henne, the man who built Jack-in-the-Box, took a standard pop-goes-the-weasel jack-in-the-box and stuck a monster glove on the end of it instead. But take a close look at that glove. The hand, with a few modifications, is Woody's.
