However you want to look at it, Tetris Attack is the Americanized version of Panel De Pon. Same concept of game, but different characters and such.
Tetris Attack appeared on the Super Nintendo, was developed by Intelligent Systems, and starred none other than the famous Yoshi, among many other co-stars that we (at the time), never heard of. The villain was Bowser, as always.
Many of you (I'm sure) have played the game at some point in your life. I assume it was pretty popular, in my town, anyhow. It had to have been anyway if they released two different versions in Japan and in America.
Here's the list of characters from both games (and please suggest any items, music or your favorite character from the game that you would like in Brawl. And if you don't like any of the ideas at all, please post so.)

I think Lip has a very good chance of being in Brawl. Her infamous "Lip's Stick" was a weapon in Melee, and her name appeared on Sakurai's Poll. I know that doesn't mean she IS in the game, but it definetly raises her chances. Panel De Pon was also remade on the GameCube as a component of Nintendo Puzzle Collection. And did you know? Kirby's "Down B" attack, resembles Lip's garbage block (the pink block.)
