Katamari Damacy is a game where you roll a ball around the map and if objects are smaller than the ball they will stick to it which makes the ball bigger, the purpose is to make new stars out of random junk. It's Japanese so of course it's weird and the theme song is kinda catchy and a rolling death bubble montage would fit it well.

Oooooh, I remember when that came out. Forgot the name. Japanese games are, um, interesting. That's for sure. =)
