Pest is an unidentified monster that even the monster scholars never have been able to identify. Does a spin attack using the covering for its eye.
- A pest is a plant or animal detrimental to humans or human concerns. Which is somewhat ironic considering a large number of monsters in Ragnarok Online fall under this description and yet this is the only monster to actually bear the word as its name.
