Mr. Grumpy is the stationmaster of Celgreb City Central.
Mr. Grumpy is precisely how you'd think he'd be like. Grumpy by Name, Grumpy by Nature. Constantly in a bad mood, he runs Celgreb City Central with punctuality and strict rules. Unfortunately for him, not everything runs like clockwork in the massive station, and he's often kept frustrated with the engines or people at the station not sticking to the rules, provoking the uttering of "Crooked Cucumbers!".
