Buddee and his friends are adventurous. One day they were sitting in the school's café when they overheard some boys talking about a cruise ship. One boy, called Aaron, was saying what crazy fun he'd had. "Besides, being an enormous ship every year, the captain puts on a spectacular show. As a bonus - each year during the grand finale there is a secret box and letter hidden somewhere on the ship, and kids are asked to participate in the search." He challenged Buddee to join the search. Buddee accepted the challenge, along with his other friends, and now they are bound for a five-day cruise, in search for the holiday secret box. Will the four find the holiday secret box in time?
