Lyrics:

Tyrone: There's something in the air and it doesn't smell so good. I wish I didn't have a nose. I'd remove it if I could!
Uniqua: You're not kidding. It smells real bad. It's a really awful smell. This swamp is super-stinky
Pablo (spoken): And I don’t feel so well...
Uniqua: But we gotta get this message through and to the other side! There's only one thing we can do: hold your nose and say P.U.!
All: P.U.! Look out! P.U.! Watch out! P.U.! Better jump! P.U.! Sure is stinky!
Uniqua: I've never smelled a smell like this. It's like a hot dog rotting in the bun! Or like the smell egg salad makes when it's left out in the blazing sun!
Tyrone: Don't let the bubbles get you or you'll be stinky too...and nobody that you know will wanna be friends with you
All: P.U.! Look out! P.U.! Watch out! P.U.! Better jump! P.U.! Sure is stinky!
Uniqua: It smells like garbage
Tyrone: Like dirty diapers
Pablo: Like moldy cheese
Uniqua: Like mushy peas!
Tyrone: Like dirty socks...
Pablo: On monster feet!
Uniqua: Or sixty-seven-day-old meat!
All: P.U.! Look out! P.U.! Watch out! P.U.! Better jump! P.U.! Sure is stinky! P.U.!
