Ok rumour has it that when Rockhopper comes back to Club Penguin he will have a new background to give out. I found all this stuff out from Wwe Adam so if this is false don't blame me. Click the link to see the new background http://wweadam.com/wp-content/uploads/2009/05/rockhopper-background-peek.swf
*UPDATE* YOU CAN ONLY GET THE BACKGROUND FROM THE BIG FOAMY ROCKHOPPER AT DISNEY HOLLYWOOND STUDIOS.
