This book tells about five unlikely animal friendships in sanctuaries and zoos, from around the world: Kenya's Owen the hippo and Mzee the tortoise; South Africa's Themba the elephant and Albert the sheep; California's Koko the gorilla and her kittens; Virginia's Kumbali the cheetah and Kago the dog; Ireland's Ben the dog and Duggie the wild dolphin.

All through the hippo night, hippos play with great delight.

"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."--from Amazon.com.
