This particular Monster Plant can only be encountered in the Spencer Mansion's greenhouse. It has no determined HP value, so its relation to Chris' and Jill's levels are indetermined. With its most powerful (and only) attack reaching 20, it will take seventy and forty-eight attacks to kill the two S.T.A.R.S. members, respectively.
Due to the unique nature of this enemy, no weapons will kill it.
Strategy
For the sake of convenience, the Player is advised to simply poison the water fountain with the "Chemical" before obtaining the collection of Green and Red Herbs.
