Victory fanfares?

[Crappy Blue Luigi]

Pokemon could use battle music varying by the game they come from.

Pikachu uses the original fanfare, Mewtwo uses gen 1 trainer battle, Lucario uses gen 4, Deoxys uses gen 3, Pokemon trainer uses a modified version of the Pokemon theme song, Jigglypuff uses... Sing.

Those could work.

Also, Waluigi is kinda tricky. My current ideas are as follows:
1. First five seconds of Heeeere's Waluigi! from Mario Party 3. - http://www.youtube.com/watch?v=rZNgp39XUKI
2. The Grand Prix finish fanfare from Mario Kart: Double Dash.
3. Superstar fanfare from one of the Mario Party games.
