This is a picture of my SIL last December filling a box of Mr. Potato Head parts
for her son. There is a Mr. Potato Head laying on the counter next to her, as well as samples of some on top of the containers.
For a price (in December it was $18) you fill up the box, and whatever you
can fit & still close the lid is what you take with you. It's less expensive to
purchase the head at Target, or some other similar store, and buy the arms,
shoes, eyes, hats, etc., etc., and fill up the box with those pieces. The
hands at the DCA store can hold the Mickey bars & other props whereas
the "normal" Mr. Potato Heads are sold are closed & cannot hold anything.
You can see in the pic below some of the pieces that are offered.
