Crabs and Mystery Truck

Giant crabs attack and shop girls and bikini clad chicks flee for their lives.

A catering truck is not likely to stop the crabs much.

What can we do?

How is the mystery submarine involved?

The crabs are huge and scary.

They clamber over buildings and toss cars aside.

They are pushing through the parking lot.

Flipping cars like they are nothing.

But what is this?  A mystery truck arrives?!
