The fact that Bo Peep was even in the movie is suspect due to the fact that this was a boy's room and toys. I have a daughter and she doesn't have any cowboy or space man toys. Maybe I should force her to play with her brothers toys and vice verse.
There may have been a Mrs. Potato head in the movie too but this persons argument would really be about the state of toys in America and a boys bedroom.
who knows, maybe sister put bo-peep there. the same sister who cross dressed buzz lightyear. it's not a bedroom, just a playroom.
