Their a rare/ uncommon spawn. They are mainly found down south in max of a pair of two. But their usually found alone. They are a passive non-agressive tame that wont flee. (They wear hats too). Have fun!
It is tamed in the same way as the Hesperornis, where you have to carry a dead fish to it. Larger fish, and those caught by Ichthyornis, apparently work better. Piranha are better than coelacanths for taming, and salmon are better than piranha.
Just push this cute lil creature in front of a giga and it'll have an existential crisis. Realising the path of destruction it left in its wake and deteriorate in front of the otters blue sparkly marble eyes
I once had an otter that I named harry otter , he was a great otter he got me all the silica and black pearls I needed, he once saved me from a megalodon , he kept me warm to, he was a great companion I took him almost everywhere,but one day I was farming pearls with him I threw him at a fish to get pearls from it but instead he disappeared I looked and looked for him only to not find him but uneven got a message that he was dead, he's still out there somewhere, I still look for him to this day. #prayforharryotter
