Nommy Monster

The Nommy Monster is a mysterious entity that dwells in the Chat Tower, feasting upon the sleeping bodies of lurking members. It was first identified by Xetaja. The Nommy Monster's victims usually have no memories of their encounter with the beast upon resurrection. Xetaja and ChocolateEevee are the only two known survivors of a Nommy Monster attack. The Nommy Monster is also known to speak in MACHOMAN.
It has two known weaknesses: CHOP Sticks (not to be confused with chopsticks) and lemons (especially if thrown at its eyes). However, upon defeat, it provides no gold and very little EXP.
