The caravan family are spending their summer in beautiful, sandy Seagull Cove. They are staying in their caravans, right at the edge of the sea, and are going to have the best seaside holiday ever! But a new friend, Benjy, is with them and he's not very cheery! Will he ruin the children's holiday, or can they cheer Benjy up and help him enjoy the seaside?
