Toadette finds herself on Drop-Road Dash. When you're ready, drop down to the donut lifts. Mummy-Me will start following you. Dodge the Biddybuds and grab as many coins as you can. If you need a short break to walk on solid ground, be sure to keep moving. Towards the end is a tall stack of coins. Walk in a circle or figure eight to grab the coins while dodging Mummy-Me. Near the end is a boost pad and a narrow path to the Star. Near the Star, you'll find some coins.
Special Challenge: Collect 190 coins.
