If I Ran the Zoo Dr. Seuss

When young Gerald McGrew visits the zoo, he discovers that the exotic animals are "not good enough." He says that if he ran the zoo, he would set all of the current animals free and find new, more bizarre and exotic ones. Throughout the book he lists these creatures, starting with a lion with ten feet and escalating to more imaginative (and imaginary) creatures, such as the Fizza-ma-Wizza-ma-Dill, "the world's biggest bird from the island of Gwark, who eats only pine trees, and spits out the bark."
The BOOK
The illustrations also grow wilder as McGrew imagines going to increasingly remote and exotic habitats, capturing each fanciful creature, and bringing them all back to a zoo now filled with his new wild animals. He also imagines the praise he receives from others, who are amazed at his "new Zoo, McGrew Zoo".
