"Got this for my daughter (4 years old) and she loves it! She assembled it with the help of my son (6 years old) in about 15 minutes. I love how the castle folds down. The book appears to hold up to play and serves to keep all the pieces together nicely. They both thought this needs a Sven reindeer for the sleigh. I just wish they had other books besides the princesses. My son really wants one now, and would be ok if they had the only princess he likes (Rapunzel), but alas. Unless I am missing something, are there other lego storybook adventures besides the four princess ones?"
