I'm uploading these so people can use them to learn mesh editor. To get to mesh editor, go to items (the tree icon), then click the little white arrow next to the yellow modes tab, then to modify them click the screw driver + gear icon, then click the item. Once you're in mesh editor, click the wrench + gear icon named mesh, then from there do CTRL + A (to select all), then click the Deformation option. Mess around with it and learn how to make mesh editor routes! :D
