Herbert loves the slide, and in this first of four irresistible miniature full-length picture books, the littlest readers are introduced to new friends and the charming world of the Hippo Park playground.

Herbert loves the slide! Climbing up the ladder, sitting himself down, sending Teddy down first—it's all the best part. Herbert imagines sliding down into a magical underwater world and being chased up a mountain by a bear—preschoolers will love Herbert's adventures playing on the slide, and thrill to this first visit to Hippo Park. 

All four Hippo Park Pals mini picture books are set in the playground, where the animals play, imagine, and have lots of feelings—just like preschoolers do.
