Level 9 took me a while but I eventually figured it out. What I did was build a skinny tower on both sides using spaghetti legs to support it from tipping over. Once you are 2 full spaghetti lengths above the ground send out 1 spaghetti arm from each tower to the middle and attach with a marchmallow. Now you have effectively made an arch. Add some support and spring strainght up to get the rings.
I am having trouble with level 12. I don't get it. I made a ramp connecting the box to the frog and made him eat the hard candy...i figured it would get his tounge stuck or something. But no. Can someone help me in figuring this out? Getting to the point of frustration - wish the game would be more specific about what it wanted me to do with the candy instead of making me do trial and error....
