I tamed a few of these thing (some got stuck so they died) and idk if it’s a bug or intentional, but LITERALLY NOTHING ATTACKS THESE LITTLE BUGGERS NOT EVEN IF YOU ATTACKS IT. I’ve killed plesiosaurs with these things. They’re OP (also for no reason at all I call these buggers dolfins)
The first time I saw one of these, I was on a rock in the middle of the sea taming a Pteradon. It came close, scared me, and since I thought it was aggressive, I gritted my teeth and bravely killed it. Shut up, noob's mistake.
