The Great Pyramid of the Earth is a monument in ancient Mexico. It houses a large boulder that can be released with the push of a button.
The pyramid is mostly light brown and gray. Pizza Delivery Girl Tasha remarks that it looks "run-down." Moss and shrubs can be seen growing on the exterior. Inside the pyramid, there is a stone sculpture shaped like a reptilian creature connected to a ramp leading up to the top window. There are four entryways to the pyramid.
The Great Pyramid of the Earth has appeared in one episode of The Backyardigans: "Chichen-Itza Pizza" from season three.
