Kronk is a human male who serves as a guard, a snack provider, and chef on main line passenger trains.

Though he can be a bit dim-witted at times, Kronk is genuinely good-hearted and friendly at his core. He's also a really good friend to those who come and go onboard whatever main line passenger train he's assigned to work on.

His voice should at least come close to sounding like Patrick Warburton.
