Miss Perkins is happy to be the 'zoo-brarian' at The Lending Zoo, a 'zoo-brary' that lends out all types of animals--from massive elephants to majestic giraffes. Everything usually goes smoothly: water buffaloes, snakes, parrots, and more are checked out and returned without a problem. But one sunny day Pancake, the tiger, goes missing and Miss Perkins along with her new friend Molly must go on a citywide search to find him! Will they be able to track him down before he causes a commotion all over town?
