Enemy Defeat Animation Not Completing

I have an explosion animation loaded onto a barrel object as a defeated animation. I set the barrel up as an enemy that can be destroyed by a character bullet, but the full animation sequence doesn't play upon defeat no matter how many frames I include in my animation and what the speed of the animation is.

Any ideas?

 

try to drop animation as an object decoration and make it spawn every 1000 don't drop it as an image
