I’m liking this series, especially since something similar to this actually happens on some island somewhere. Google it, and I’m sure you can find a picture of a street running red/orange with crabs.
Please go on!

fantastic. I can’t decide whether to be worried or laugh. Maybe laugh and run away. Keep going!

Thanks for the tip, Fyora. It seems that is true, on a place called Christmas Island. The pictures are quite similar to what I’ve imagined here, only my crabs are, you know, evil. ;-)
