The popular Siamese returns as a stowaway on a jaunt with ``The Man'' and ``The Kid.'' When hiding below makes Henry queasy, he comes on deck to enjoy the sights (including dolphins and a whale), ascend the mast, note how the small craft is sailed, and play a crucial role in rescuing The Man when he falls overboard. The story is slight and predictable, but it's smoothly told by this old pro, while the carefully crafted realistic illustrations (remarkably precise for watercolors) are sure to appeal to Henry's fans and other cat lovers.
