Sinbad (Tyrone) is sailing to find the end of the rainbow. Pablo, a young, inexperienced sailor (and a huge fan of Sinbad), sneaks aboard to help him. When Sinbad discovers this, he is upset, as he has always sailed alone and doesn't feel he need any help. Indeed, at first, Pablo seems like only a bother, causing the loss of ship's supplies, forcing them to take detours where they must play games to earn new supplies. Pablo, however, refuses to be daunted and searches for a way that he can help his idol.
