Is this possible?

Yeah it's what Original said above.
I did it too with a LOT of monsters ( also like the "hatman"in Premonition )
There is a function to get an animation to work.
Here take a look at this :

SetEntityActive("PigRunAfter", true);
AddEnemyPatrolNode("PigRunAfter", "PathNodeArea_6", 2, "");
PlayPropAnimation("PigRunAfter", "streets_sc7_cloth", 0.0f, false, "");

The ( streets_sc7_cloth ) is the .anm inside the enemy\animations folder.
