Hello Kitty Roller Rescue - GameCube

The menacing Block-O dreamt of conquering the universe, and decided to leave his planet, Planet Cube, and head for another galaxy in search of his next target. Unexpectedly, Block-O discovers that the inhabitants of Earth like to give out gifts. Once the gifts are received, gift boxes are usually thrown away. Misinterpreting the gift box as his beloved kind, Block-O resentfully dispatches troops to invade Earth and win justice for his fellow cubes.
