I bought this toy for Christmas my son, who wanted absolutely that disappointment. It has never been able to play because the skull carlo do than jump, I think the spring that opens the skull is too powerful or that the skull of the closure system is not strong enough. The system of "boogers" is not great either, we tend to draw SEVERAL of a sudden and then it's quite difficult to catch the "mud trap!" I regretted this purchase, besides, I have not kept. I do not really recommend this toy.
