The Garden of the Clinging Vines (also referred to as the Garden of the Twining Vines) is located in the Land of the Mangaboos and is used to get rid of unwanted visitors.
The garden contains a mass of tough green vines all matted together, twisting and writhing like snakes. These carnivourous Clinging Vines crush anything they touch and devour their victims to make themselves grow bigger. (Dorothy and the Wizard in Oz)
