Truckee is a Dalmatian and the mascot of the Sesame Street Engine Co. She appears in the 1991 Sesame Street video Sesame Street Home Video Visits the Firehouse. During lulls between calls, the firefighters wash and scrub Truckee, leaving her too damp when duty calls. Big Bird offers to substitute as a "fire bird."
The dalmatian has been used as a stock dog puppet on Sesame Street, and was recycled as Bill Dawg and the watch dog salesman in Sing, Hoot and Howl (performed here by Jim Martin). Other appearances include Episode 4152 and "Hot and Cold" with Katy Perry.
