It seemed like it was going to be funnier...
This wasn't anything particularly interesting. The song was really quite annoying as all fuck, and the smurfs didn't do anything eventful. One spun around behind the others with a trumpet; that's about as far as it went in the realm of 'action'. You need to add more stuff to this. It also took forever to load--you have a lot of shit to work on here, my friend.
the song gets annoying quick, and all you did was make the heads pulse, smurfet turn and harmony (I can't believe I remembered that) appear randomly. Nothing special. If you had more too it, I would vote higher. Nice job though. You can improve this, so give it a shot!
