But Musa beats Oso to the briefcase, and Wolfie launches Oso off the boat after hearing him talk. That's when a special alert comes in. Two kids, Zack and Chloe, are at a fancy dinner party to celebrate the wedding of their aunt Mary and uncle James, but Zach doesn't know much about using good table manners. Oso must teach Zack good table manners to show Chloe how polite he is.
