I think the main theme of Blockland may be of some kid's toys "gone wild" or something. How ever, it depends on how you potray the game. Such as, a freebuild in the bedroom, or some realistic zombie survival or deathmatch.
On another note, "stirring stuff up". Seriously!?
And now that I think about it...
Yeah, the blockhead looks very close to Rayman, but I don't think I've seen anyone dressed like him, that I remember.
