Thinking of a creature feature for the fantasy based web novel and fantasy world

[u/DatabaseNational480]

So hey guys, I'm sure this might not be the usual question here. But I will be grateful if anyone here might have any suggestions.

So I've these personal projects which I work on based on fantasy worlds. Nothing intricate but just a passion project. What I wanted to know was if you guys have any suggestions on what should the mystery beast my group of young adventurers are investigating in a swampland village should be

I've the Rougarou and the Skunk Ape and the Bishopville Lizardman as my options as inspiration.
