I had heard of people using Mr. Potato Head parts for pumpkins, but I did not want to buy a bunch of Mr. Potato head parts. Then I found these, made just for pumpkins. I could only find them at KMART, I looked at Walmart and Target and did not succeed. They are actually only $3.99, but I bought 3 packs, so the kids could have a big variety. I only used half of them, if that. These entertained two three year olds for an hour (they did not leave their chair once). Best part, they could do it completely by themselves. I love carving pumpkins as much as the next guy, but with a helpless three year old, it can be the pits. This was so clean (I actually got the entire kitchen really clean, while the kids did it at the kitchen table), they are interchangeable, I can save them for next year, and I think they turned out pretty cute. I could even save my pumpkins for Thanksgiving if I take the parts out.
