There's a small green frog on a half-sunk log in the middle of the bog. He eats one tick, two fleas, three flies, four slugs, and five snails. And the frog gets a whole lot bigger. Then a hungry gator shows up, ready to eat the big fat frog. The frog opens his mouth wide to scream and out comes everything he's eaten! And the frog gets a whole lot smaller. The gator swims off, the frog keeps away from the log, and the insects keep away from the frog....

Summary: Dot and Jabber, mouse detectives, try to solve the mysery of the disappearing insects.
