The Kackel Dackel Game is both educational and icky as the object of the game is to watch a plastic dog poop out its "food."
By squeezing a pump handle, the "food" runs through the dog's body and out its bottom. Perhaps kids have a lot of fun catching the feces? Regardless, this game sure is an interesting toy to help kids learn about the digestive system. The Kakel Dackel Game can be seen as literally crappy, but fun at the same time!
