The erroneously-named dancing shrimp

Whoever christened this particular creature ought to be frog-marched (heh heh) straight down to the trades description offices pronto. Honestly, I stood watching this little fella for ages and he might just as well have been superglued to his rock for all the dancing he did. I mean, even with the DJ blasting out The Chemical Brothers "Galvanize" at full volume, did Mr Shrimp bother to shake a leg? No he bloody didn't. Frankly I'm disappointed.
