Bucket is one of the elements in Farm Heroes Saga. Water buckets appear on the board usually when you need to collect water droplets. The buckets are provided as a way to replenish a board with the droplets. To do this you must make 3 different matches alongside of it. When this happens, you will receive 4 water drops on different spots on the board. Water buckets can not be moved or destroyed.
When you are creating your matches alongside the bucket, try and make the matches count towards your cropsies needed to complete the level. You can also use a shovel speed up the process of overflowing a water bucket.
The drops will not be spread on eggs in all their stages. They can also be filled by filler companions.
