wart gnome
A once considered mythical creature that lives in the oversized and distracting wart on the end of a nose.

Only a wart gnome attached to a waron has the ability for mind control. The gnome often is perverse and has a one-track objective.

The waron walked up behind me and then the wart gnome ordered him to put his hands on my body. Gross!
