Angry Birds: Golden Egg Number 17

The seventeenth golden egg is in Ham'Em'High, level 12-12. You will see what it'll look like, but I have to tell you how to get it. All you have to do is destroy the gold trophy thing.

Well, that's about it. I guess I'll see you next time!

P.S.(postscript) I advise you to hit the balloons holding the TNT shown in the picture.
