Any crustacean experts out there?

We ended up in Pegwell Bay today (we were going to go to Sandwich Bay but £7 to get through the toll?! You can shove that up your arse, ta) and aside from seeing a Viking Longboat, we came across loads of these things. What are they? Tell you what, we are thinking about seeing if we can start a zombie LARP group there, it'd be perfect! It's eerie how empty and disused it is, it'd work perfectly!

Anyway, happy fourth anniversary to me and Nick =)
