Loompa Land is the former habitat of the Oompa-Loompas.
Loompa Land is a dense jungle filled with trees and vegetation, but relatively devoid of wildlife, mainly because mostly predatory animals, such as the Hornsnozzlers, Snozzwangers, and Wangdoodles, live here. Because of this, Oompa-Loompas live high up on the tree tops, being safe from the animals above but also risking death by falling.
Willy Wonka went to Loompa Land in search of ingredients, trying out everything that he can find, including the blood of a Wangdoodle he had just killed with a machete and green caterpillars. During the search, he came across the Oompa-Loompas and, seeing their predicament, offered to bring them to his factory.
