Good afternoon all
I was just deadheading my petunias after a week of neglect and found this hidden away inside the pot

Not sure how a bird would even get in there, the plant was like a jungle. Not really sure what to do, I guess I should leave it where it is.

I left it on the ground. It was gone in the morning, hopefully planted more sensibly
