The box was a little moldy, apparently it had gotten damp on the bottom at some point, but the inside plastic tray still looked fairly clean. I think it all works fine, it did when I put it away. If you're worried about mold just toss the parts into a big bowl of boiling water with dishwashing detergent and you should be fine.
If nobody with an actual child claims it in the next day or two I'll give it to whomever wants it.
I can probably tag this post with a photo later if I remember.
