Teddy Fitzroy must solve the crime of the kidnapped rare and expensive panda, Li Ping.

Teddy Fitzroy returns as FunJungle’s resident zoo sleuth when a rhinoceros is at risk in Big Game, a follow-up to Belly Up and Poached—which Kirkus Reviews called a “thrill-ride of a mystery.” When someone takes aim at Rhonda Rhino, FunJungle’s pregnant (and endangered) Asian greater one-horned rhinoceros, the zoo steps up security measures in order to protect this rare animal and her baby. But the extra security isn’t enough—someone is still getting too close for comfort. Teddy and company start to suspect that whoever is after Rhonda is really after her horn, which is worth a lot of money on the black market. For the first time ever, the head of the zoo enlists Teddy for help—for once, he doesn’t have to sneak around in order to investigate—and the results are even more wacky, and even more dangerous, than ever before.

Join FunJungle’s resident zoo sleuth, Teddy Fitzroy, as he solves mysteries and strives to protect the animals at the zoo with the first three funny and suspenseful novels of the bestselling FunJungle series from New York Times bestselling author Stuart Gibbs, now available together in one collectible boxed set! It all starts when the hippo goes belly up—and it’s a wild ride from there. When Teddy Fitzroy moved into FunJungle, the nation’s largest zoo, with his scientist parents, he expected things to be kind of quiet. There’d be the occasional elephant stampede and water balloon fight with the chimpanzees, of course, but when Henry the Hippo dies from not-so-natural causes, Teddy suspects foul play. And that was just the beginning. He begins to realize that the zoo is far more exciting than he thought it was, and soon the mysteries at FunJungle are piling up... This collectible boxed set includes hardcover editions of Belly Up, Poached, and Big Game.
