Cumulus Isobar

Cumulus Isobar is a minor character from Big Thunder Mountain Railroad at the Magic Kingdom. He is a so-called ‘rainmaker’, a snake oil salesman, who lives in Tumbleweed.

Background
Cumulus Isobar came to Tumbleweed amidst a terrible drought. He promised to bring back the rains for a price. Before he could make off with the townsfolk's money, a flash flood hit the town, trapping him there.

He can be seen in Tumbleweed, emptying water from his caravan, while the rest of the town enjoys the water.

Trivia

 * Isobar is believed to be a caricature of character designer and Imagineer Marc Davis, though this has never been confirmed. The gags in Tumbleweed are possibly inspired by his concepts for the Western River Expedition, which was going to be built on the land that became Big Thunder Mountain Railroad.
