Vivid art helps make this picture book a preschool story hour favorite. The art and simple text about fish in the sea help introduce comparison words.

"On a deep-blue background, the words 'blue sea' appear, and then the first of Crews's eye-filling paintings. The author and illustrator of Rain have invented another winner." (Publishers Weekly)

As a 5-star review puts it: "A delightful book to help the beginner/elementary reader learn simple comparative and superlative adjectives. 'Small,''Smaller,' 'Smallest,' and 'Big,' 'Bigger,' 'Biggest' are mentioned in this 21-page story that averages about 3-4 words per page. The text is large, and the visuals are simple, colorful, and uncluttered."
