Inside I discovered a snail's dressing room full of different shells.
I know that this is a dressing room because snails are actually Hermaphrodite's - they are basically trannies. And as trannies they need a lot of different outfits to wear.
Whichever snail lives here is not particularly fashion forward as it's shells are all very brown, but I think it might be an elderly snail so these will be vintage shells. This is good news.
