Do not kill something in the water near a tamed sarco on aggression target, it will glitch the sarco to spin around in circles and will eventually pick you up and possibly crash your game. It’s cool though.
Good mount to take into rivers and even the ocean. Good for hunting fish and I've even seen it beat a megladon. But never use it to fight a Rex because if things go south it is a very slow land mount. Short and sweet it is a hunting mount
TLC patch coming March 2018 adding "Deathroll" grab attack on small creatures and a grab attack (possibly thrash) on larger ones, gaining a 180 degree attack and a small lunge to its attack (maybe for deathroll purpose), will no longer aggo pirahnas and in the wild will sit with mouth gaped open awaiting prey. Like so people can see!
