Cindy Bear gets ownership of a dude ranch, and all the animals come to help her get it ready for the guests. But a bad guy named Mr. Hothead (who goes under the name Mr. Coolhead) uses his invention to make all the animals except for Yogi, Cindy, and Boo Boo lose their tempers. Since they can't work together, the boys won't finish their jobs in time and Mr. Hothead will trick Cindy into selling him her ranch. Will they learn to work things out in a calm way without losing their tempers?
