You'll need to harvest a certain number of sweet honey jars to reach your goal, by having them reach an exit point (at the bottom of the board, where there are arrow indicators). Boosters and power-ups can't be used to collect honey jars, they must be harvested via the exit point.

Bear in mind, if the level starts with two honey jars, then only two can appear at any given time. Collect one or two jars for more to be added to the board so you can complete your mission.
