The Lost Symphony Earth Star plays the ancient tune on the five giant icicles but fails to change the toadstools back into Toadlets. Learning that two more instruments must be found and played together, the Toad Patrol make a hair-raising descent down the big climb on a home made elevator and set out to search the valley before the spring warmth melts the icicles. As spring is coming and the icicles melt, the cure will be ineffective.
