A poor homeless gastropod...

But of course he isn’t homeless. I was following a geocache clue for a poor homeless gastropod but found this guy with a perfectly good home. He’s lucky I didn’t make him homeless to fit the clue!
I didn’t find the cache because I’m still at the stage I was with photography 10 years ago. Then I felt stupid taking random photographs of rust or something; now I feel stupid poking around in a wall looking for what is presumable a toy slug...
