content: I bought this toy for my son for Christmas. I had bought some of the "trucks" and wanted him to have Bob and Wendy too. I found this set and thought it would be great. They ONLY good thing about this set is that he has Bob and Wendy.The clicking blocks sound like a great concept, but they don't work. If you can get them to click you are lucky. You can not build anything with this set. The box shows a house, buildings, etc., but you can't build these thing because the magnets are in the wrong places and the roofs make the whole thing top heavy!I would avoid this set unless you just really need Bob and Wendy (like us).
