 He is the only human in the films to observe toys actually coming to life, when near the end of the first film, Woody and Sid's mutant toys decide to rescue Buzz by scaring Sid, which causes him to become frightened of toys.The last straw is Woody coming alive while Sid is holding him and telling him to "play nice".This causes Sid to panic and run back into his house screaming, and then to his room when his sister scares him with her new toy doll, Sally.
