This is a tip from the "Potato Head Queen" as dubbed by the cast member @ Once upon a Toy. I did not see them at World of Disney on my trip in May ONLY at Once upon a toy (they have the Disney My Little Pony's too, but that's another story for another time

. Anyway, here are the absolute most important tips I can give you about getting your $$ worth of Potato Head. 1st, buy the actual Potato Head body at Wal-Mart or Toys R Us (Wal-Mart has the Darth Tater out and is less than $8.00 plus comes with cool Darth Vader parts). Anyway, on with the story. If you buy the body at Disney, that alone takes up 75% of the total box space...no...no...no!!
Get all the parts you want (don't put them in the box yet) and start a "pile" on the counter. Don't be stingy, get all the parts you want. Especially get the arms with the cupped hand, these arms are the only arms in the universe that are compatible with Disney balloons, ice creams, etc. Once you have gotten all the parts you want, carefully and methodically, place them one by one into the box. Doing this makes the absolute most of the space in the box. Some of the items simply don't fit well (goofy ears, or Buzz lightyear space ship) so I made some changes. I did omit the buzz ship but did get the goofy ears. After a few minutes of careful placement I got everything I wanted in the box. At the end, there were a few "empty spots" which I filled with small items like ice creams, name tags, arms, etc. My box weighed nearly 2 pounds!! The cast member who checked me out said I had the heaviest and most full box he had ever seen (even better than he could do) and dubbed me the Potato Head Queen. Sadly, I am proud of that honor. Anyway, hope this helps. Same advice for the My Little Pony kit!! have fun
