Mushroom Run is the second stage of Treat Land in Kirby's Epic Yarn and Kirby's Extra Epic Yarn, unlocked by completing Toy Tracks and using the Hammer Patch. This stage involves a winding path through numerous bouncy mushroom platforms, along with swinging mushrooms and a few mushroom houses. Completing this stage yields the Cake Patch, which is used to unlock Sweets Park.
Upon tossing the patch, a large hammer appears and swings into the ground a number of times, causing mushrooms to appear in the background. The door opens once this concludes.
Overview
The stage begins with a simple walkway past a few red mushrooms, which demonstrate their bounciness in a relatively safe manner. Further in, the path turns into a cave, where the springier yellow mushrooms can be found. Here, Kirby should learn that using the Weight will allow him to gain a greater bounce from the mushrooms. Sea Jellies can be found up ahead and, while they cannot harm Kirby directly, they can release spores on him that temporarily immobilize him. After a few more hearty bounces forward, Kirby will stumble onto hanging mushrooms that swing back and forth, he will need to traverse these to move on. In the last area, a few mushroom houses can be seen at the bottom of a huge array of mushrooms which lead upwards. Kirby will need to bounce from one to another to get to the top, where the Bonus Bell can be found to clear the stage.
