The Rainbow Brigade is here to help! This group of dogs led by Nubby-Bean brings smiles, joy, and hope to people going through difficult times, whether it's dealing with a new baby sibling, a best friend moving away, or the loss of a parent. Bodhi has a baby sister who receives a lot of attention from family and friends. Now, he is feeling insignificant and forgotten. When Nubby-Bean and the Rainbow Brigade show up at his door, they try to show him that the most important job in the world is being a big brother. Does Bodhi learn to embrace his new role?
