While we're talking about Tetrisphere, we might as well talk about the music. It's pretty good, right? Almost makes you wish that there was more. As luck would have it, there is!

This is actually two tips in one, but I'm getting a little ahead of myself here.

First, create a new profile.

Where it asks for your name, hold down L, C-down, and C-right. You'll notice that some of the characters turn into goofy symbols. Tip #1

Enter your name as 'GAMEBOY', substituting the little alien head for the letter 'A'. And you'll hear a sound like you did something, with no immediate indication what it might be.

Head to the options screen, though, and start scrolling through the songs and you'll notice that a few show up with silly names.

They're not really very good compared to the rest of the songs in the game, but you might find one you like if you look hard enough.
