Yes, it's time we put you out of your misery and revealed what last week's Item of Interest actually was. Despite cries of it being a facehugger (LẌ), an albino's penis head (Hound), and Winnie the Pooh cosplay porn (yes, thank you, Mr Peenee), the item in question was...
A sea gooseberry (scientific name Pleurobrachia pileus)!
These little blobs of jelly can be found around the coastlines of Great Britain and northern Europe from early summer to autumn, often washed ashore where they gleam like jewels on the sand.
