I will make a list of pros and cons about this creature:

Pros:

Nothing, and I mean NOTHING will aggro to you, even if you attack it

Inflicts torpor

Can melt armor, harvest dead bodies from afar with acid ball

Swims the same speed as walk

Cons:

Terrible weight (100) you're going to have to stuff your whole inventory somewhere, and maybe even your armor

Saddle requires 35 obsidian

Something I've noticed:

Wild ones can deal constant (like .5 sec between attacks) damage to you, but tamed ones, not even mounted ones can, and I get this needs to be balanced, but make it only work on wild creatures or something, I would love to see it work
