Shoggoth Animation

I need a Shoggoth stand animation? It may or may not be a simple task for some. It needs to do a pulsing-like animation, like it has a giant heartbeat. [More detail (This is optional if you have a better idea): It's body bulges, but it's eye bulges out even more, as does it's mouth.],Yeah, that's it...

Here is the thread for those who hasn't seen it yet.

If you want to animate it, tell me, and go on MSN/AIM and IM me and I'll give you the Shoggoth.
