Because of its dark and shady environment, Viridian Forest hosts a large array of different Bug-type Pokemon. They are not particularly powerful, but they will cause status conditions such as paralysis and poison. It is advised from sign posts and even from other Trainers that Trainers should buy status condition healing items such as Antidote and Parlyz Heal before entering the forest. Pokemon such as Caterpie, Weedle, Metapod, and Kakuna inhabit trees and tall grass, allowing themselves to stay hidden from predators.
