The wishing balloons.

A young girl named Dot is overjoyed when the moving truck arrives at the house down the street, and even more excited when a boy her age steps out, offering the prospect of a new friend. But Albert looks sad, and he won't reveal why ... That night, a balloon with a note tied to its string taps her window. Unfolding the note, Dot finds a wish that Albert has written. This is her chance to make Albert happy.
