Level 21

 is the first level in Lemonade Lake and the fourth.

Special elements

 * Marmalade
 * 3-Layer Icing (first appearance)
 * Wrapped Candy (inside the marmalade)

Difficulty

 * Collecting the green and blue candies is very easy, and you already have 10 wrapped candy inside marmalades, so you only need to make two more, and with 5 colors that might be easy.
