Welcome to the first ever MASH UP. A mash up is a combination of 2 rollercoasters, the idea came from Zizz. Please nominate and 5-star if you liked it! Credits to Tike, Tedbear2, Foodsomatic, and Zizz. Also, if you have a rollercoaster idea you want me to make, say it in a comment below, I might make it! :)
