First Appearance

Yellowstone National Park, often referred to simply Yellowstone Park, is a national park located primarily in the U.S. state of Wyoming, though it also extends into Montana and Idaho. Yellowstone was the first national park in the world, and is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park. It has many types of ecosystems, but the subalpine forest is dominant.


The park is covered with many green trees with brown bark. Its ground is normally covered with grass, dirt, or sand. Its waterfalls are full of blue water, and its lakes and water ways are filled with transparent, sometimes blue-colored, water. High cliffs are normally colored gray or tan.


Yellowstone Park has been visited in one episode of Wonder Pets!, Save the Egg!.
