It has been raining for a couple of weeks. DAVID tells us how they can forecast the weather. DAVID and LISA have to go to Holland, where it has been raining for so long that 70 hares are trapped and about to drown. With the help of gnome WART, his wife BRENDA and their two children, they make six rafts with the magic rope and this way they are able to bring the hares to mainland safely.
