I have just two words for you: "Loco" and "Roco".

I got to play a demo of this game over the weekend, and holy cr@p that's a fun game.  It's everything a handheld game should be - super easy to control, visually interesting, challenging and completely ridiculous.  It's the kind of game only a Japanese developer could have developed.  It almost makes me with I had a PSP.

The game is simplicity itself - you're helping to guide a bouncy yellow blob through the world on its quest to collect stuff.  While you do this, the blob sings this very cheezy and catchy Jap-Pop song.  Control consists of two shoulder buttons that tilt the "world" left and right, and an "Action" button that either explodes your little blob into bloblets that can pass through small spaces, or forces those bloblets to reform into one blob.  Incidentally, the bloblets yell as they're reforming.  It's hilarious.

Words really can't express just how strange, addicting and funny this game is.
