S3E2 Bright Heart's Bad Day

Champ stops Mr. Beastly from sabotaging the Care Bear Family picnic and dumping food on Brightheart, which prompts Beastly to seek revenge. Throughout the picnic, Beastly continuously disrupts Brightheart’s enjoyment, even though he’s surprisingly winning the events instead of Champ. After Beastly sabotages his chances, Brightheart becomes disheartened and wanders off to a cave. Cheer, Treatheart, and Champ set out to find him but end up trapped by Beastly in the cave. In a twist of fate, it’s Brightheart who devises a clever plan to help everyone escape.
