I'm trying to raise my king’s stats and I have a bunch of egg yolks, ya know, sounds like a perfect match!
But you'd be wrong. In order to consume an egg yolk, your lion has to be hungry.
As a solution, I'm proposing the idea of an item that makes your lion hungry!
I read somewhere in a book that yarrow, I think, can make a feline throw up. Not sure tho, never tried.
So I was thinking, maybe the items could be called an herb bundle, because yarrow is an herb. Once you are it, the text at the top of the screen would say a little something like this:

[Lion's name] looks at the bundle of herbs, disgusted. With one final glance at the yucky leaves, [Lion's name] laps up the leaves quickly. After a while, [Lion's name] starts to look a little green. [His/her] body convulses and you see what you think was [Lion's name's] latest meal laying on the ground.

I hope you like it! If you don't feel free to tell me why! (Optional, duh)
Have a great day/night!
