How do you make fireflies fly in Farm Hero Saga?

Question

How do you make fireflies fly in Farm Hero Saga? I missed the explanation on the first level they appear and now I'm stuck.

Fireflies are made to fly away by all being lit at the same time.

@alip have you reached the roadblock? You need to go back to level 1056 and get at least two stars in rancid to unlock the roadblock. A little tip for you, the more moves you have left, the higher the score you get :)
