The mission occurs in west central Sunbeam Plains, and involves picking up dropped Mushrooms for a delivery Toad three times. The first is timed for forty seconds, and involves a zigzag Mushroom trail and three piles of Mushrooms, the second is timed for thirty seconds and involves a straighter path and two larger piles, and the third is timed for twenty seconds and simply involves one big pile. Once the third phase is cleared, the Toad will rush off to Peach's Castle, thus ending the mission.
