Here are some crops that I would like to see in the future.
Brussels Sprouts
In-Game Description: It tastes bad, so it must be good for you!
My Description: Gives a large energy boost, but causes an equally large drop in mood.
Cactus
In-Game Description: A thuoughly spiky cactus. Petting not suggested.
My Description: You can either eat it for an energy boost, or you can drink the water inside for a mood boost. Or you can pet it. Go ahead, I dare ya!
I'll add more in the future! Suggestions are encouraged.
