Monday the Bullfrog is an interactive children's puppet book by author and illustrator Matthew Van Fleet, published by Simon & Schuster. Designed for preschoolers, this unique hardcover combines a hand puppet with a concept book, teaching young readers about the days of the week through an engaging story about what a friendly bullfrog eats each day.

The book slips onto an adult's hand so the cuddly bullfrog character becomes an animated puppet with an opening mouth. Each day of the week, the frog encounters and devours a different colorful plush critter — including a butterfly, mouse, crab, caterpillar, firefly, and fish — attached to the pages as tactile, squeezable appendages. Children can explore different textures, colors, and shapes while following along with the story.

This multi-sensory format makes it an ideal gift for toddlers and early learners, encouraging interactive storytelling, imaginative play, and early literacy. The ISBN is 9781442409583.
