Johnny Boo is the best little ghost in the whole world, because he has Boo Power. This means that he can go 'BOO' really loudly! His pet ghost named Squiggle has Squiggle Power, which means that he can fly and do really fast loop-the-loops. Together they have the world's greatest ghost adventures! And now, for the first time, the first five books of the full-color, all-ages hit series is collected into one handsome slipcase edition, JOHNNY BOO'S BIG BOO BOX!
