Sneakers's human family takes him to the ocean where he has a cold, wet experience with the sea and makes an unsuccessful attempt to catch a fish. "So Sneakers decided to go out in a field and look for mice instead. The field was full of butterflies, so Sneakers chased one."
The day continues as he walks away from a looming seagull, chases shrimp, and watches the fog roll in. Mortimer's exquisite paintings are a lovely complement to the text, with golden spreads of the black-and-white cat, the creatures he encounters, and the sea.
