When Wally first becomes invisible (thanks to the handy-dandy OOPS Machine) it's great fun. Now he can do whatever he wants, like defending Opera by humiliating a bully, or helping the local football team come back from a 0-54 score. But the fun and games are short-lived when everybody from a crazy ghost buster, to the FBI, to the '59 1/2 Minutes' TV show, to the neighbor's new dog (a cross between a grizzly bear and a Tyrannosaurus Rex) begin pursuing him. Soon Wally is stumbling and staggering through his greatest misadventure ever ... until he finally learns that cheating and taking short cuts in life are not all they're cracked up to be. Until he learns that honesty really is the best policy. Recommended for ages 8 to 12.
