On 49 you have to use the triple ball and aim it at the second LCD, that should knock down the 2nd lower painting, then get the fireball to hit both paintings.
YES
for level 33,
You rapid fire 3 balls at the top row, that should knock them off, then you bank 2 balls off the ceiling at the picture. (put your mouse on the could 2nd to the left, on the top right of it, the pointy part of the mouse on the tip of the inlet on the top right of the cloud.) It should work, takes a while though.
That's weird.. I didn't have any trouble on 24.. 33 is the hard one....help anyone?
On 24 you just aim straight at the Picture but shoot very softly, so that the outside balls tap the microwaves, and the microwaves fall off really easily. It's a trick shot, that's what the level's called, you don't have to go for the most expensive block.
