actually there is possibly something, you might be able to use the play data of someone who had unlocked the levels. But you would have to convince someone who did the work to give/sell you the data on sd card. I cannot help then on the grounds that I still need to unlock some of world 9.
This just came to me, having just woke up.
I would still really recommend playing through on your own or enlisting the help of friends.
