Level 431 is the sixth level in Rainbow Runway and the 102nd ingredients level. To pass this level, you must collect 2 hazelnuts in 50 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The multilayered icing and chocolate can prove annoying. However, you have 50 moves to bring down two ingredients, which should be plenty to complete the level.
If the ingredient(s) are dispensed by the dispensers in the middle, then you have to switch it to the exit.
