It threw me when my six year old asked for a body for Christmas. When he explained he wanted to know how the body works, I found this and I am beyond satisfied with this purchase. We do this often and we read the book that comes with it. The only way this could get better is if it came with a case to hold everything. He likes that the body parts are squishy and I like that he's learning while playing. The Organ-izer is one of his favorites. He likes knowing what everything is called, and I like the book that helps with proper placement of the organs. I would buy this one again!
