What's Burning?

Day 1:
In the dining room-
What is that smell?
It smells like plastic or rubber.
Maybe it's the new table cloth?
Day 2:
Seriously, the smell in here is awful.
Maybe the outlet is shorting out. Let's unplug the computers...
Day 3:
The smell is still here and it really smells like burning rubber!
As Ken is lying on the floor wrestling with the kids, what's that blob in the ceiling fan light?
Hmmmmmm, it's a melting rubber dinosaur egg that Brad "lost" 3 days ago.
