Hydra

Hydra, the Chief, and friends

Hydra is a dalmatian who appears in A Visit to the Sesame Street Firehouse. The dog, whose gender is unspecified, serves as the mascot for the Sesame Street Engine Co., curling up for a nap near the feet of resting firefighters. Hydra eagerly says goodbye to the Sesame Street gang, mimicking the Chief's hand shake.
