Grades 3-5. Spot and Sue, two hyenas living in Africa near a safari camp, slowly learn how to understand and then speak English. When a human couple on safari are eaten by crocodiles, Spot and Sue seize the opportunity. Walking on their hind legs and disguising themselves with clothing, the two hyenas take on the humans’ identities—their names (Mr. and Mrs. Bold), passports, even plane tickets home to England. And that is the start of their adventure. They settle in to a quaint British suburb, secure jobs, and have two pups, er, children, all the while hiding their animal nature from everyone except perhaps their nosy neighbor, Mr. McNumpty. In its quirky, unique way, this explores themes of family and what constitutes human nature. Filled with jokes and body-related humor, and illustrated with many pencil drawings by Roberts, this entertaining tale will make readers chortle. A good choice for reluctant readers and fans of Captain Underpants.
