After starting the course, the player receives a Super Mushroom. Throughout the course, the player is on bridges between ground pieces. On the second set, the player can jump on a Red Koopa Troopa and kick its shell to take out two Goombas, three Green Koopa Troopas, and three Buzzy Beetles, while also bouncing on two sets of Trampolines. If the Shell goes unhindered, it takes out a few more Goombas before falling in a pit. However, if the player grabs the Super Star, they can take out the shell. After grabbing the Super Star, all enemies are stacked on Goombas. After the Thwomp, all enemies on top of Goombas are Big enemies. The Goal Pole is one gap across from Big Bowser.
