What do you do at the end of Super Smash Bros. brawl?

there is no real "end", thanks to multiplayer mode that can be played by one person. At the end of SSE, just try to get 100% on each stage. After the subspace story go back to the forest and two other special levels. Go into the first door you find to start a movie. I the forest you will fight toon link to unlock him. In two other levels you have to fight wolf and jigglypuff.
