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.

Although there are laughs to be had in Dr. Dolittle 2, its preoccupation with toilet humor and Murphy's restrained performance makes this a missed opportunity.
