Started on the base for feet. Took the seats from original PW car and cut in half. Then noticed an interesting concept with the back rest flipped over, could pass for a foot. Processed a few ideas in my head and came up with idea for using both parts of each seat as Foot bases. Going to use some rubber mat material for sole, great for traction, and maybe add some blocks to gain 6 to 8 inches in overall height.
