[Help] Is it possible?

You could probably do it. It'll probably require a lot of work though. I got a spider to follow me around a while back. That took a good long while. It was really funky because I had to switch between two entities so the critter would face weird directions.

Anyways, yeah you could probably make it a water lurker monster type, since I don't think you lose sanity when looking at lurkers. Lurkers can't be assigned path nodes if I remember correctly...so you'll have to use "food" entities to get him to move.

Edit: that'll also cause issues if you want more than one critter, because they'll both probably chase the food, so it'll be hard to control them. But anyways this is just off the top of my head.

Actually, Water Lurkers can follow pathnodes and they drain sanity. This is proved on the Cellar Archives and Archive Tunnels.
