Dragon Putdown started as Dragon Rider. Dragon Rider was a monster truck that looked like a dragon. I changed it because it wouldn't work . Why you ask? Well for one it was too heavy. For two the chain kept slipping. After all attempts I changed it. Next I made a building that turns a tire. I also made a smaller dragon rider, except it doesn't have a motor. The dragon goes under the tire and shoots out the other side and can knock down something.
