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.

Andy and Kip head to the Galapagos Islands in the Pacific Ocean for a wild adventure in search of marine iguanas. These lizards eat seaweed that grows on rocks on the sea bed and, using his underwater rocket on his gadget pack, Andy follows some iguanas on a deep sea mission. He also discovers they have a rather nasty habit of snorting sea water out of their nostrils and gets soaked in the process. Luckily Kip's wondrous wet-wiping windscreen glasses help to keep some of the splashes off his face.
