Level 1592 is the twelfth level in Vanilla Valley and the 400th ingredients level. To pass this level, you must release 2 gummi dragons in 20 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The cake bombs can help clear the frosting and bring the dragons down.
However, if the dragon is in the same column as the frosting, at least one layer of frosting is required to be removed before/after activating the cake bombs. Moreover, even if the dragon is the same column as the cake bombs, the outer-most frostings can make the cake bombs hard to clear.
The first dragon must be brought down before the second spawns.
The dragons are worth 20,000 points.[1] Hence, an additional 30,000 points is required to earn one star.
