Yoi don't have to actually add up the animations. As long as they do one of each of them, in any order, you're good to tame. Head shake, trunk shift, and ear flap. This thing could do 3 head shakes in a row and then do an ear flap and trunk shift, you're good to tame. It HAS to do all three animations or you get wrecked.

If the deinotherium is taking beer but you are getting no taming progress, put only 1 beer in your hot bar. - Lyx
