At the end of the animation, it seems to loop back to the start.

Also, unrelated, but I am currently unable to post on the MCF thread, and your picture on there is blank to me. Not sure what happened there.

The MFC issue seems to be on your end only. Also, I cannot view the video.

Edited the link. Does that one work?

Yes. That end animation is the popping animation. If you look in the texture file its an animated texture for the bubble, same as the fire focus animation.
