Haven is a good game but it could be a great game if it had Otters.
After all, what is an online game if you don't interact with otters? ... Ok. Sorry.
Anyway, I'm suggesting this because otters:
Could be a new "pickable" (no combat) critter;
But slightly difficult to get like... water rabbits.
Maybe they could bite a bit or such (wounds like crabs/hedgehogs) -- or worst case scenario, fight as well (around the same strength of swans, I guess)
Could have its own meat, possibly sausages with pun-y names (Like "Frankfotter") and maybe some sort of SCARF (with the whole hide) and be the first/only gildable face slot (the one for mask, talisman, glasses...) how about it?
Finally, if you are lucky enough to see two otters spawning next to each other, they could randomly reach and hold hands.
Witnessing that could be a new Experience Event! (Called... "Significant Otter" Hah! Great, right?)
...
Otters, please?
