Destructo!

One of Ace's early games -- invented and promoted by Mommy -- was the rapid de-construction of any tower with a swift left hook, deemed "Destructo!"

Not only can the lil' wrecker now say the word with relish, he can also take a moment to gaze mischievously into space before laying waste to this fine tower.

Note, in the background, Elmo's obvious terror at what is about to happen. He knows he could be next.
