And found this!!!
Took it home for my eldest son, Angus, because I thought he'd love it - he seemed less than diverted.
Hey ho - beats the crap out of a heap of shells and a crab skeleton, if you ask me!
Oh, and in case you're wondering - it's a rusted up aerosol can of who knows what (hopefully nothing too toxic), which must have got pierced either before or after it's nautical adventure and the solidified orange stuff is it's erstwhile contents.
