Trivia

 * 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.
