Frog Cap In The Leaky Lake
Frog Cap in the Leaky Lake is the cap switch course that unlocks the Frog Cap. When the moat is drained, the player can swim into a hole in the Castle Grounds lake that will lead to the Cap Switch course. It is a large underground lake. At the bottom of the lake is a light green Cap Switch that unlocks the Frog Cap in courses with water. There is also a red coin star.
