RTF is a global modification that replaces all towns in the game.

Not bad at all 👍. I just don't quite understand at what point the animation cuts off. Does it stand up and hit three times in a row? Or is it just a repeat to make it easier to view?

It's just looped. I rotated it from different angles, and it animated in a circle...
The Yeti stands up, hits its chest, lowers, and when it puts its right leg forward - that's the end of the animation...
