Oh.....Hi Mommy

Mommy was working on the computer the other day while I spent some time playing with my blocks. Mommy had been showing me how to build towers and knock them over (I think you adults call it some fancy word like "implosion"). I got a little bored with the blocks so I decided to check out the remaining contents of my toybox. When Mommy looked into my bedroom from the computer this is what she saw.

I heard Mommy snickering so I grabbed what I had in my hand and sat down, acting like nothing was out of the ordinary.

Mommy takes hints rather well. Can you tell from this next picture what I wanted?
