Here's a crash-course for the uninitiated: de Blob takes place in the once-colorful metropolis of Chroma City, where the nefarious I.N.K.T. Corporation has sucked the color and music of the town away. It's up to a ragtag group of rebels to bring the funk back to town and rescue its enslaved inhabitants. Enter our hero, de Blob, who can absorb paint and literally wants to paint the town red: anything de Blob touches turns his color.
You use the nunchuk to steer de Blob and the Wii remote to make him jump and do a Sonic-esque homing attack. Stages are large, open environments with a variety of missions within them, from covering entire buildings in a particular color within a time limit or defeating specific enemies.
