"Nalle is one of the worst beasts documented on the Bear Registry. As the Registry puts it, 'nearly half of this bear is a mouth', a maw capable of swallowing a person whole. That claim is not hyperbole; the team that documented Nalle lost one of its members that way. It's likely that more souls have been lost inside that pit which defies belief. On the registry she is listed as
not slain.The beast cannot make out what is directly in front of her. Like a baby, her main form of interaction with the outside world is to put it in her mouth. As both offensive and defensive reaction, sustenance and threats alike are taken in without testing for wholesomeness.
This tendency to swallow anything without discrimination can be used to advantage to eliminate Nalle."
"Nalle is active in an area with many trolls, which often spew half-chewed and defecated gobbets of infected material everywhere they go. With so much pressure from the harsh environment, many other creatures are desperate for any scrap of sustenance they can obtain, and mistake the strewn spew for a savoury stew. Thus, swallowing these is a major vector toward spreading the contagion in the area.
What you must do is gather together bits of the offal strewn about by other these trolls and place it into the back of a stony cavern. If you raise a clamour around Nalle, she will feel as though she is threatened on all sides and will retreat into the cave. Once inside the cave, she will hear her own thrashing and roaring echoed back at her. Alarmed, she will back further into the cave, stepping into the offal piled there. Her limited vision will be of no help to her as she becomes maddened by the terrified grunting and growled threats she hears in the echo chamber."
"Your team should now back away, keeping a defensive and watchful position outside the cavern.
Inside the cave, Nalle will become aware of the offal piled around her, and probing it with her tongue, will mistake it for something that will sustain her. Every noise she makes will resound in the echo chamber, and she will be beset by a frenzy of eating and growling, still believing herself surrounded by enemies. When she encounters her own back foot, covered with offal, she will become completely enraged at the pain of her enemies' bite, and
attack."
"By the time she realises it is her own feet and backside she's stuffed into her maw, it will be too late. Like an ourobouros, she will eat herself. And that, will be the end of Nalle. Now, are there any questions?"

(We can hope this team (with or without blue hair) manages to move Nalle on to the forests of Tapio and Mielikki where she belongs, soon.)
