What's in your drink?

Monday morning, as Tim made his coffee, he looked down in the Keurig and happened to spy:

"Hmmm, what could that be?" He pondered aloud.

 "WHAT IS THIS?" He asked more urgently. Because it was so melted. Like a few cups of coffee had been made over it for who knows how long.

Yeah, we have no idea how this googly eye made it into the coffee maker. Wait. Yes, we do. We have children. No further explanation needed. (Right?)

(Please say yes. Otherwise we're in trouble and need to call Ghostbusters.)
