In part one of the two-part season finale, Meghan, Rachel and Peter threaten mutiny unless Lee joins them in singing a hokey song. This week’s episode features two new stories: "The Great Wallaby Adventure," a feel-good, island groove about discovering mini-marsupials, by Illinois neighbors Olivia, 5th grade, and Marissa, 8th grade, and "Presents for Mom," the terrifying tale of two brothers whose gifts for their mom go a little too far, written by California brothers Max, 3rd grade, and William, Kindergarten.
