Chief and Rockapella in “Unfinished Business”

This is Kneemoi.

(singing) Kneemoi

Her face is cute but she's unsavory. Watch out for her knack with knavery. Her last known whereabouts: California. Pinus longaeva is Latin for long-lived pine, and it's a perfect name for the bristlecone pine trees in the White Mountains. Some have been alive more than 4,000 years and that makes bristlecones the oldest living things on Earth. Why, some of these trees were around before the Egyptian pyramids. Dense resistant wood is what helps them weather eons of ice, sand, and drought, and even when bristlecones do die, they can still remain standing for centuries. Or they did until today...

(singing) Ooh!

...when noxious Kneemoi careened into California to knock on wood, then she branched out to breathe in the bristlecones, and before you can say another pine mess, every last bristle was gone. She plans to sell the trees on Roddenberry as a nasal decongestant. Gumshoes, you've got to get rough with that stuffed puff and solve today's case...

(singing) Woo-woo-oo-oo

...SHOO, TREES!
