A group of beavers ask Dr. Dolittle to save their habitat from loggers. The only hope is to get the forest preserved because it's the home of a protected bear, but there's a problem: the bear's the only bear in the forest, so she can't reproduce. Undaunted, Dolittle persuades a circus bear to help out, but he has to teach him not just the ways of the wild, but the wiles of lady bears too.
