NPCs

Non-player Characters(NPCs) are monkeys where you spawn on spawn points. NPCs go out and pop bloons on their own. They have their own properties. To spawn NPCs, press the bag icon or the Q button to open it. Then on the spawn point, press the NPC you want to spawn. The NPC will spawn but you have to wait for the half-second cooldown before spawning another NPC. You have to buy the NPCs on the shop where it says NPCs and structures, then the NPC section before buying the NPCs. Different NPCs have different costs.

Upgrade paths
NPCs have ten upgrades you can access for your NPC. After the ten upgrades, you can choose one of the three paths like the players. These specialist paths have five upgrades. Unlike the players, the NPCs have no ability.
