From the journals of Dr. Johannes Krug:

In my traverses I have seldom come across such intriguing creatures as the ones I am next going to introduce to my readers. Truly remarkable faunae!

The individual Tundra scurried away as one of my assistants approached him bearing offerings. It vanished into the undergrowth nearby only to reappear behind my unwitting lackey decapitating him in the process. Following the beheading this creature started off into some kind of a dance. After following it briefly I believe it to be a ritualistic one. Shamanic, even! With strong pelvic movements.
