Those are Fritos Corn Chips shoved inside of the tape player. Needless to say, this has now become one of Connor's toys and will not be used for the purpose of playing music ever again.
Besides, who uses tape players any more...Connor would just think of me as an old person. We're in the modern age now! He'll look back at this picture and ask me why I didn't save the tape player, it's a classic item that you can't find anymore. I can just imagine it now.
