Bought for my granddaughter for her 1st birthday. She loves it. Collect this torment. Not because it's difficult, but the instructions are terrible. It's black and white and the parts are colored (of course), but some parts are identical but in different colors. So you can't tell which parts of the guide to use! And you REALLY need to pull some of those pieces together. When I saw that you needed a hammer I decided I wouldn't need it. I have made. Oh and stickers! There are so many of them, and some of them go in a certain direction unless the directions tell you, of course. Once he's stuck there, he's there.
