The Bob-Whites are off to the Ozarks to spend some time with the Beldens' Uncle Andrew. Trixie can't wait to explore some dark, damp, and most of all, mysterious caves, because she has another scheme up her sleeve. A national magazine is offering a reward to anyone who can find three 'ghost cave fish.' Nothing will stop Trixie from finding them - not bats or wild cats or even a real ghost!
