19 Moves (revised)
4 Poppy Flowers
The hardest part about this level, isn't getting the flowers, its getting all the crops needed.
You must use combinations and +5, and have cascading crops to get the extra value on that you need.
Move the bull in as few moves as possible, it will help if you have extra moves for the crop gathering. You actually only need to use one bull, take him round, starting at the top left flower in a square.
Use shovels wisely. Its always a good idea to save one to the end, in case you can move a crop to make a match to get the last few crops you need.
