OK so for those of you actually looking for tips.
1: it can eat 50 at a time so take 50 with you each time.
2: it hold mounts only for a little bit so if you can, just hop back on the turtle quickly and swim away till the next feeding
3: once you tame it beware manta s and anglers as the tuso cannot hit them while they glitch into the head of the squid. It's not that hard if you prepare to lose everything and keep trying. It's worth it once you do but you will need escorts to help with mantis and anglers such as megaladons.
Use a Mosa to tame this beast. Let the Mosa get grabbed wait a couple seconds get off feed it black pearls. Have your mosa on follow lowest, swim a bit away from the Tuso after feeding it, when the Tuso lets go the Mosa will swim to you. Repeat until Tuso it tamed. Super easy!
You need two people, one for feeding the black pearls and the other to feed the turtle that is in the grasp of the Tusoteuthis, with sweet vegetable cake for the health and to feed it stimulates berries as well
