While stealing firecrackers, Barry and Valerie take refuge in a giant child's balloon, which is cut loose. Mark and Steve hop in, and the balloon is inexplicably drawn west, against the wind and across the 'Sea of Storms'. Dan and Fitzhugh can only listen helplessly as the rest of the group is drawn out of range.

The little people come upon a friendly giant who mistakes them for leprechauns. The giant, O'Reilly, assists the little people in obtaining items to help repair their chip, and the group becomes embroiled in a series of adventures with policeman Krenko.
