Teenage Mutant Ninja Turtles: Color Classics #2 (Volume 2)

'The Unmentionables.' On the snowy streets of Northampton, a bored Casey Jones has gone from vigilante to old-school gumshoe, prowling the quiet streets looking for a case. He gets his wish in the form of a stolen golden cow, a kidnapped April O'Neil, and Slovakian mobsters! Can the Turtles bail him out of this misadventure of bovine proportions?
