It's not a glitch. I solved it without any boosters. Here's what the deal is. To get all three yellows you have to go through basically 3 layers. The plastic wrapper, then the check mark then the yellow candy. You can use anything to open the plastic wrappers such as striped candy or color bombs. BUT when the wrapper is off you have to use two more of the same color to unlock the yellow. Once it is yellow you can use anything to crush it. So it's a matter of luck and working on getting the bricks on the right side down so you can carefully let those checked candies fall. If you use other things on them they have a 50% chance of turning into a whipped cream block. Or whatever that is. 

I don't have the answer

I have the same problem!

Please, help me!
