What Stinks?

Ok, here's a fun game you can all play along at home.

Something stinks here. I mean, RIGHT here. Under my computer table or something. It's definitely somewhere in this little corner of my basement.

My kids say it smells like the penguin house. Since I'm not housing a penguin, and I really doubt my cats caught (and killed) one, I'm gonna have to say that's not what it is. So ... what do you think it is?

Sure, I could move the table and solve the mystery for myself, but where would be the fun in that?

Winning guess gets whatever it causing the stench mailed to them.

You're welcome.
