As a Super Mario fan growing up, I enjoy seeing the my children play with the same characters that I spent so many wonderful years with. I have often found myself sitting on the floor getting in on all of the game-play action with the K’NEX Nintendo Super Mario 3D Land Prongo Building Set, reliving my childhood memories. This set was more complex, then other building sets we have owned, while my son does enjoy playing with it while it's complete, he did need help putting it together. Recommend someone at least 8 or older to put it together, but they may still need assistance Just like the game, start at the warp pipe entrance and use the jump panels to move Mario throughout the course. There are hidden rooms with a trap door panel and a pop-up Goal Flag at the end, just like when you complete a level in the video game, and don’t forget to catch all of the coins and Star Medals!
