Farm Valley Merge

I have 2 animal/plant cards that do NOT have a picture of an animal or plant on them.  They are blank, does anyone else have blank cards.  Do they do anything, should I keep them?  

Also on Farm Valley - what is up with that useless pile of hay taking up my pastures.  I want it gone its useless.  You know anymore I think POGO is useless.  Maybe we have to pay to get rid of the wheat.
