Link, Sonic and Pokemon = Crazy Music Videos
Legend of Zelda:
Done well, but some of the sprites went a bit too fast.
Sonic:
Great music! And it was cool to see Sonic with a guitar
Pokemon:
I can't say I'm much of a pokemon or a polka fan but the finished product of their combination turned out well.
Although I'd have to agree with MysticShadowX's statement about the epilepsy warning (LOL).
