Chief and Rockapella in “Unfinished Business”

This is Robocrook.

(singing) Robocrook

Don't be fooled by his silvery paint. One thing's for sure, the Tin Man he ain't. His last known whereabouts: the Milky Way Galaxy. A galaxy is a bunch of stars, planets, gases, and outer space dust bunnies held together by our friend Mr. Gravity. The Milky Way Galaxy is the intergalactic address for our solar system and perhaps billions of others. Celestial bodies revolve around the Milky Way center, much the way our planets revolve around the sun. Now why is it called the Milky Way? Because the view of the galaxy you see from Earth looks like a milky haze spreading across the sky. Or it did until today...

(singing) Ooh!

...when Robocrook showed his fairest face in outer space. That heister hopped on his hyper Hoover, switched on the suction, and glommed the whole galaxy, then he staged his own test of the Big Bang Theory. Gumshoes, you've got to round up Robo and solve today's case...

(singing) Woo-woo-oo-oo

...STARDUST BUSTER!
