Are you sure it's not just a snail spinning it's shell against the glass?

I'm certain it's not a snail. This is a re-occurring noise. I'm hearing it frequently. It's too loud to be a snail.. but good call.

Most definitely not a snail... I hear the clicking way too much for it to be a snail.

PS: The rock is spoken for.
