Ninja Monkey/Strategies

Conclusion
Ninja Monkey is an awesome tower due to its good early game and being good at speed control. None of its upgrades are totally useless. Its ability Sabotage Supply Lines is extremely good in late rounds either in BTD5, Bloons Monkey City Contested Territory or Bloons TD Battles to control MOAB class bloons' speed.
