Two hyenas from Africa find a pair of passports (memo: do not go swimming in a crocodile pool), and move to Teddington, England, where they live suburban lives, hold jobs, and raise their children to hide their tails and act human--the only trouble is old Mr. McNumpty, their nosy neighbor, who is hiding a secret of his own.

The Bolds, a family of hyenas masquerading as humans, have problems during a camping vacation at the beach, including stopping a dognapper.
