Otters can protect you from cold climates drastically, they eat up all your depression and aren't hard to tame at all! Just catch some Sabertooth Salmon or Piranha and bring the corpse to the otter and feed it. There you have your very own cute little otter. But remember to Bola it so it doesn't run away first. About 2 just in case. Kill one and I'll find you on multiplayer...
These little guys are so much easier to tame in mobile, but harder to find. You still need to kill a megipirahna, but you don’t need to grab its corpse to feed the otter. After harvesting its meat you can easily walk up to it and feed it until it’s tamed. It doesn’t run away in mobile, and I’m sure you can use any fish meat. Like so Dododex sees!
best to tame a ichthyornis and carry it with you when looking for one of these guys, put the ichthyornis on hunt and retrieve it will catch a fish and bring it back golden and will have a better taming affect to feed to otter, like this up its very important peeps must know :)))
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
