I've been slashing grass every now and then in my house and thought of this. I think it'd be cool if we could buy wheat seeds or something similar that act as a furniture item. You plant them in your house, then after a while they are fully grown, and then you can cut them down for gralats.

Perhaps the seeds could cost 2 gralats each, they could grow in 30 minutes and when slashed they give 5 gralats and disappear. Alternatively they could cost around maybe like 50 and give 1 every time you slash it and it would grow and regrow in about 5 minutes.
