Then exit the Bubbulfrog tunnel and go to the southeast wall, and climb up to find the tunnel that was above the Like Like. You will find an area with buttons on the ground. To learn the correct buttons to press, you can visit Dueling Peaks North Cave. Remove the rocks that are currently on the buttons, then place rocks on the correct buttons, and the door will open, revealing Misko's Treasure. Open the chest to get Tingle's Shirt.
