The trick is to figure out the pattern - the nuts drop on the turns 4-8-12-16. So you need to manage and arrange your candies to drop on the sides on these turns. After you have all nuts in proper columns, you need to activate your frog as soon as possible - can start doing it in between the turns above - then blow the little square and hopefully that should be enough (was for me). Took me a few days to finish this level :D And the girl who uploaded this video was very lucky with the bombs :o
