Careless Cobblins

The Cobblins - you know the Goblins that inhabit the drains and 'unknown' spaces beneath our town - have become even more careless than usual.

I spotted one of their pots left behind in the cracks of the Cobbles on Sunday.



When I looked more closely there where quite a few others that had been left behind.

Can anyone explain their behaviour?

Are these messages that have been left to cheer us up?

Are they just testing out whether we're fully awake as we doddle around are streets?
