Mr. Potato Head and My Little Pony are at Once Upon a Toy at Downtown Disney. If I remember correctly it's pretty close to BBB. It's right by Earl of Sandwich and the huge pin store. In February a box of either was (I think) $18. You don't have to get any ponies or heads. DD7 fit two ponies and TONS of accessories and pony clothes into one box. Some of the pony accessories are huge and we didn't get any of those... I am a potato head nut and have filled 8 or 9 boxes of pieces on our three trips. My favorite thing to do is grab a basket and put the pieces I really want into it. I then go to an empty corner, dump the basket and pack and repack the pieces until I fit as many as possible. Yes, I am nuts, but that's MY fun souvenir.
