Animal Control IV

Well then, here's a change of pace. There is a parasite invading the packs of night wolves in the indigo plains. (These plains are turning out to be really dangerous huh?) They appear to be spreading to the slightly hallucinogenic forests and the mountain range to the west. Find a way to destroy the parasite without decimating the animal populations, do not let the parasite spread far or infect you.
