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.
