I think I took like 6 or 7, got tired of breeding the sloths. And I typically heal "during" the fun, my theory is that hopefully everyone makes it out, or if Iv underestimated and trying to makes sure that we make it out of the arena alive. Sides, its no big deal to roll in on the backside of everyone, use all the reserves the pig has, take a step back and devour whats in the inventory for another roll up. Now with that said, mom was on one of the yutys doing the roaring. So the plan is still implemented the same as a megatherium setup, just with a little variety.
The yuty's wasn't as high as I was hoping, wanted them over 8k health, I think. The one I gave to mom however was nearly 20k.....literally spent every single point in health and nothing else.
