Professor Sunny Showers: The host of the attraction. A brown-haired man in glasses and a lab coat, Professor Sunny Showers knew all that there was to know about meteorology and hoped to inspire park guests to go into the field as well. Unfortunately, he didn't count on the other characters - simply referred to as "the weather" - getting in the way. His voice was provided by Gregg Berger.
Mr. Sun: A big, yellow, cartoony sun a la the mascot of Raisin Bran, donning a pair of sunglasses. Mr. Sun was laid back, a bit of a wisecracker, and sort of like a surfer dude personality-wise. He sang a catchy Beach Boys-esque song, "Hotter Than Hot", about the sun. His voice was provided by Frank Welker.
Rain: This was the physical representation of rain, a shower of raindrops with a face. Rain was melancholy, a dour type, and thought of herself as the most important weather because so many animals and plants depend on water to survive. She sang a blues number, "Rainy Day Blues", about why it rains. Her voice was provided by BJ Ward.
Snow: The air in the theater chilled as Snow, taking the form of an anthropomorphic snowflake, entered the theater. Snow was always in a good mood, loving to brighten the days of boys and girls everywhere by coming to town (and cancelling school in the process). She claimed to be good friends with Jack Frost and Frosty the Snowman and sang a Christmas-y jingle called "White Stuff". Her voice was provided by Katie Leigh.
Cloudy: Cloudy was, fittingly, a large blueish grey cloud. He was an excitable fellow, able to shapeshift, and loved a good joke. Of the weather, he was the most humble, believing that all types of weather are of equal importance and happy to take the day off and let Mr. Sun or Rain do their thing. He sang the jazzy "Sky High" and was voiced by Lennie Weinrib.
Wind: A gust of wind signaled the announcement of, obviously, Wind. Wind usually took the form of a few curved lines (wind is usually represented by that), but could turn into a tornado if she got angry... which she did. Often. She was good friends with Rain, and performed the Latin-inspired "Blow You Away". Her voice was provided by Susan Blu.
