Hux was running away from the First Order's land to teach Ren and Snoke a lesson (that they are nothing without him, so hands off, Kylo, you don't have any right to beat me up!!!) and met something on his way in the middle of the night. Something very big, very carnivorous and very hungry.
Now he has to prove that he is, in fact, worthy of his Cave General title.
A short-faced bear went extinct almost 11 000 years ago. He had lived in the North America. This bear was very, VERY big - almost 3 meters tall standing up (8-11 feet), and while on his fours, he was still able to look a grown man in the eye. Weight: almost 1 tone. He was far larger than any other bear in the history of this kind.
He was probably exclusively carnivorous and needed at least 15 kilograms of meat per day. He wasn't picky - being a top-predator, he could hunt every animal he wanted - probably including early human.
So yes, Hux is in trouble. He had won with a giant turtle - can he do it again with this beast?
Also, happy St. Patrick Day :) and I would like to dedicate this picture of our fierce, ginger warrior to theGeneral Hux Appreciation Day promoted by @firstorder-humanresources-dept
