O-1978: 💚⭐[Leechsona] The Devourer⭐💚

Known as The Devourer, this massive Cavie eats people and other leeches, and has become a local cryptid in his area of residence. He stays in an old mine shaft that the town hadn't used for decades

They say if you wander too far in, you'll never come back out

He's gotten too fat from eating people to really be able to get out of said mine shaft though. He too damn thicc to squeeze through the tunnels, he's stuck in an inner den he dug years ago

~~~ 

At some point a much smaller Leech finds him, and starts to bring The Devourer offerings in hopes of befriending him. Well, it works! The two become a bonded pair, and the little Leech eventually digs his massive companion an exit 

Once surfaced, the duo wreaks havoc on the town who's mineshaft The Devourer had been stuck in, snapping up anything that moves within his jaws

When the town is cleared out, they claim it as their own
