It appears to be Earth with a lot of green land. There is also some water. There is a city on the top, a tree on the right, a volcano on the bottom, and some pyramids on the left. The background is spacial, and the track path is transparent.

- In the portable version of Bloons TD 4, bloons come from the bottom right and finish at the bottom left instead. Also, the land and water formation on the planet itself is vastly different.
- Despite the terrain being Earth, in real life, Earth is about 71% water and 29% land, while in Bloons Tower Defense 4, there is more land than water, at least at the side the track is pointing.
