Gakster

Apposed to a Plimbus, a Gakster is a creature that is NOT TO BE TRUSTED. Often described as being unpredictable, often hostile, determined, and of high intelligence.

If seen anywhere, DO NOT APPROACH.

"Hey man, I hear stories of a monster roaming around, do you think they're true?"
"Hell no. Nobody sees Gakster and lives to tell the tale."
