Fraggle Rock (1983)

S4E2 Wembley's Wonderful Whoopie Water

Wembley possesses a unique ability: he can hear water hidden within the rock walls. When Gobo and Red doubt his claim, he embarks on a mission to prove them wrong. As the water eventually bursts forth, the Fraggles realize it’s unlike any other. However, when the water triggers rock quakes and Gobo falls into a fissure, the group must decide if it's time to put an end to their exciting adventure.
