This level is such a fun easy one, its likely to be a good one to go back to when we are stuck with newer ones.
Episode 54 introduces the river. On the river sails logs with crops sitting on. Everytime you make a match of crops, the river moves so the logs move on a space.
It might sound harder than it really is.
Use the crops on the logs to make rows with crops on either side. Watch the video if you are unsure.
Once the log has sailed past, you will have to match elsewhere if the crop is wrong.
Try and make as many matches as you can on the grass in this level and you will get the extra points you need.
