Truly Impoppable Difficulty



 is a term referring to the Impoppable tile difficulty in Bloons Monkey City. All tiles that contain camo and/or at least Lead as the highest ranked bloon are considered Truly Impoppable if the player does not have at least one tower or upgrade (read: not having built at least one base building for the tower or not having researched the appropriate upgrade in one of the upgrade buildings) that detect camo bloons or pop lead bloons, respectively.

Regardless of stated difficulty, all Hills Terrain and Snow Terrain tiles become Truly Impoppable if the player only has Dart Monkeys available (either by having not built other types of base buildings yet in the early levels, or having all buildings damaged due to MvM attacks and leaving the player with only Banana Farms and free Dart Monkeys). Conversely, all tiles may become Truly Impoppable if the player does not have access to free Dart Monkeys and has all buildings damaged from MvM attacks.
