What's Up, Mom? (1992)

Bridgette is sad because she thinks everyone has forgotten her on Mother's Day. Jonesy explains the holiday to Buttons and Rusty and they decide they should do something special. Venturing into the forest, they chance upon Mother Nature who's being finicky with weather. After the cubs present her with a gift, she makes the day beautiful for all of Chucklewood Forest. A Mother's Day feast follows and everyone celebrates the occasion.
