"It's Drizzling, It's Pouring" is a song from the episode "The Heart of the Jungle".
Tyrone: It's drizzling and raining and dripping and raining, we're trying to search and explore!
Pablo: But we can't 'cause it's raining and pouring and raining and teasing and raining some more!
Uniqua: Don't worry, you fellas! I brought my umbrella, and this is specifically why: it's big, it's terrific, and it's scientifically proven to keep us all dry! Please stop your complaining, this light, little raining will end in a minute, I guess!
Pablo: You call this a little? It's up to my middle!
Tyrone: Well, what do you call it?
Austin: A mess!
The water's increasing with no sign of ceasing, I'd rather be warm in my camp.
Pablo: Then here when it's raining and dripping and raining and soggy and raining and damp.
Who knows where we'll float with a leaf for a boat in the rainy and watery damp?
