Character mistake: Mr Potato Head gets torn apart by baby Molly after the opening scene. When Andy returns to the room with Buzz everyone resumes their positions, but Mr Potato Head looks for his bits and sits under the shelf with the other toys.
Suggested correction: I don't get it. When Andy and the boys are going to his room, all the toys scramble to get back into place. Mr. Potato Head is missing his left ear, and he slightly panics. When the boys get to the room, Mr. Potato Head is under the crib with his left ear back in place; he found it off screen. It's appropriate for him to look for any missing pieces of his before rushing back into place.
