The Sacrificial Monkey is a half-dead monkey that relies on other towers to survive, contrary to most monkeys, who can self-sustain. When placed, it will "steal" HP from other towers (organic towers only) to power its energy attack (which is like the apprentice's basic attack), which requires the tower to steal 5 HP to be charged. The basic attack pops 3 layers off up to 3 bloons. It costs $620 and has 196px of range. It can detect camo and pop lead/frozen bloons. It wont suck HP off towers with 1 HP, but can do so (thus killing them) if Relentless Mode is activated. It sucks 1 HP every half second. This tower can use multiple abilities at once (you can "toggle" them when the tower is selected), but will prioritize stronger abilities first.
