Andy and Kip embark on another wild adventure, this time to see giant bullfrogs in the grassy plains of southern Africa. These frogs live underground, only emerging, much to Andy's surprise, when it starts to rain. After witnessing a spectacular water fight, Andy discovers their more caring side and with the help of Kip's latest invention, the fabulously fun folding spade, Andy helps a daddy bullfrog to dig a ditch to help move some tadpoles from one puddle to another.
