Telly with a water glass in the conservation-themed Episode 2870.
"If There Was No Water" is an unused Sesame Street song written by Tony Geiss for Season 22.
Out on the street, Telly Monster shares his glass of water with his goldfish, Felicia (who swims around in it). He notes that it's important to share when resources are low and begins to wonder what the world would be like without such an important thing as water.
Through song, he imagines himself trying to swim on an ocean-less beach as fish walk by on their hind-fins, and boats use wheels to get around. In the kitchen, he finds that with no water, no other drinks could exist (resorting to drinking a glass of air), and then takes a waterless bath. He ends the song with verses about why he's glad to have water around, for the snow in the winter to being able to drink again.
