'It's a hot day and the Bell family is going for a swim. But when a runaway dog chases a little penguin that is waddling up the beach, Lulu has to leap into action!
Is the little penguin hurt? And as if that's not enough for Lulu to worry about, where is Pickles the cat, who's about to have her kittens? Let the search begin!' (Publisher's blurb)
