if you are a mario kart fan like me you may know the Booster Course Pass From MK8D AY Racing In WII Rainbow Road!!!-- why not you race in the last track in whole mario kart? you can add more racers. including if are 12 (cuz they are XD) the smooth things are who moves the characters smoothly characters cannot be too big or small so you should only show its head if case your character is big you can add a special animation like the Ice Cream Player character's idle can be animated
actually the map is from mario kart tour but only is looking up Mario kart
