- Star Coin 1: On the third geyser in super form, ground pound the brick blocks in the geyser above the coin when the geyser disappears.
- Star Coin 2: Jump on the palm tree with the Red Koopa Troopa and second Star Coin after the trail of blue coins.
- Star Coin 3: To the left of the last geyser, be in Ice or Penguin form to freeze the group of River Piranha Plants and walk on them. If you're not in any of those forms (unless you're Nabbit), make a careful jump to avoid touching the enemies or the spike balls.
