I used to do this before to get New Animals and Plants for free. Don't have to used farmbucks. This is string
e_deco_animated_flag_expansion
change to
e_token_deepwoods_expansion_sp
after this, change your cheat engine to arrange of byte
63 61 73 68
change to
62 61 73 68
then click enter or you can go to your neighbor and come back. But I usually click enter.
