Smaller Rock

The Big Rock as it makes its debut in Backpack as the second place.

The Big Rock is a large, blue rock that makes its debut as the second place in the sixteenth episode, Backpack. However, when it first appears on-screen, it is smaller. It is in a narrow canyon, and it has a slide on the back and a tree on the top. The Icky Sticky Sand is in front of it as well as the Troll Bridge. However, the Library is behind the Big Rock. It also appears in later episodes, but it isn't a location in later episodes and instead just makes a cameo.
