Joker towers look like 0/0 Sniper monkeys that are human snipers. There is only 1 Joker tower received in St. Bloonis Cardinals after wave ten. It has no upgrades. It has 100 HP. Parker bloons need to shoot it to destroy it. When P.A.R.K.E.R. comes close to this tower. this tower is immediately destroyed and a slimy R.I.P. stone appears where joker tower was killed.
