"The WUMP World was a small world, very much smaller than our world. There were no great oceans, lofty mountains, giant forests, or broad sandy deserts. The WUMP World was mostly grassy meadows and clumps of leafy green trees with a few winding rivers and lakes. But it was perfect for the WUMPs, who were the only creatures living there..." - [Bill Peet, The Wump World]
