Toad Patrol S02 E09 The Lost Symphony

EarthStar plays the ancient tune on the five giant icicles but fails to change the toadstools back into Toadlets. Learning that 2 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.
