That crab is ridiculously freaky. I was just thinking someone should make a horror movie based on killer crabs, then I found one on IMDB--Attack of the Crab Monsters. Here's the plot outline:

"A group of scientists travel to a remote island to study the effects of nuclear weapons tests, only to get stranded when their airplane explodes. The team soon discovers that the island has been taken over by crabs that have mutated into enormous, intelligent monsters. To add to their problems, the island is slowly sinking into the ocean. Will any of them manage to escape?"

It's time for a remake!
