Level 125 is the fifteenth and last level in Peppermint Palace and the 66th jelly level.
To pass this level, you must clear 34 double jelly squares in 33 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Even if those blockers are cleared, it is still difficult to clear the jellies there due to their positions.
However, the striped candy cannons can help to hit the side jellies once the liquorice is cleared.
One that had experience with four-layer icing or higher can pass this level without too much frustration or difficulty. However, they are not encountered for another 46 levels after this, and five layered icing is not encountered for another 151 levels.
