Metal Eating Blob

I got my old jar of mixed Silly Putty out the other day. This morning I got the ship, knife, revolver, and hat out of the Monopoly and Clue games. I also grabbed a couple ball bearings.
I turned the putty into a Metal Eating Blob! Ah!!!

I'm hungry! FEED ME!

Hmmm...that's good. I need more! I'm getting bigger...

and bigger...

and BIGGER!
