Lost blue JBL portable speaker with a small colorful keychain attached, last seen in a park in Athens.

I lost my blue JBL portable speaker while walking through the park in Athens last Saturday. It has a small, colorful keychain attached to it and I'm pretty sure it slipped out of my bag as I was taking a break on a bench. It means a lot to me, and I'm hoping someone might have seen it or picked it up.
