random idle animation and other animation ideas

There should be a quick and easy way to make an animation play at a random time while idle to make the mob feel more alive, I'm sure with the resources given I could make it work but I just wish there was a checkbox like the walk animation checkbox. And on top of that maybe some other animation type things like making multiple animations tied to the same thing for randomization similar to adding multiple sound files to one sound effect. #animation #idea #suggestions
