Hey guys! So I had some ideas for semi-aquatic mobs for Don't Starve Together since the waters have been expanded with mechanics and mobs but still hehe.
Beaver: Neutral. Fells trees in certain seasons(?). Kinda competitive for wood/log resources in those times. Can build dams(?). Hostile if attacked.
Otter: Passive. Not really befriendable but can bring you fish and sanity bonus(?). Might steal fishes in the process of fishing or something.
Seal: Not too sure about being for Don't Starve Together but more like an aspect of idea for a Don't Starve DLC inspired by colder regions (taiga, tundra, icy areas) (P.S. I know, wrong thread but just mentioning)
Leopard Seal: Hostile. Design like quite literal name.
Harbor Seal: Befriendable. Can be fed fishes. Might work like a mount on water(?) with like literal wordplay for Harbor being a place where ships are docked. (This would be analogous to Gnarwhail in that specific DLC)
