You can tame it on primitive plus but you need to make the kibble in a cooking pot. It won't work if you make it in a cauldron. Hopefully that's helpful to those that are trying to make kibble but cannot.
If you find one hovering over the water, bringing a raft near it can unfreeze it and cause it to land. Maybe even on the raft. Be ready to bola it and tame. Careful if moving the boat they might fall off
Be very careful taming this guy. Come prepared with fish meat and narcotics. It’s torpor goes down so fast, look away for a second and it’s gone. If you bola or shoot it in the wrong spot, you get the gift of watching it drown and/or be eaten by megs. I got lucky, my house boat is shaped like an L around a small open area for my bary, Toxin. A pel got stuck in that L, so I set Toxin to passive and a few punches easily took it out. I had taming supplies on my house boat along with fish meat for Toxin, so I got it after a minute
