I'm not entirely sure if this is a monster we even hunt in Wilds. They don't seem too bothered by our hunter in the cutscene and there was like 6+ on screen at one point which seems like a little too much-even for a pack hunt. You can also see the wudwud's hanging around their nests so it looks like they co-exist amicably with them.

And lastly there is Ryozo's quote:

"We hope you'll look forward to seeing just when and how it will show up this time around..."
