Acidic Jellyfloat

The Acidic Jellyfloat is just like a lesser spotted jellyfloat except it is green, can create small pools of acid that last two minutes, and kill pikmin other than greens twice as fast. Also, only green pikmin can damage it, although it will swallow bomb-rocks causing an instant kill.

Strategy
The easiest way to kill it is to use bomb-rocks for an instant kill. If there are no bomb-rocks at hand then you can try to take it down just like a lesser spotted jellyfloat with green pikmin.
