OK every time you level on Yoville you get some new trick or dance or item. Once you hit level 40 there are a few levels that you get a herb garden

at level 50 you get the "Magical herb"

Put the "Magical Herb" on the ground, eat it and woo la you turn green (like your stoned green)

Now walk around town tell ppl that you are stoned and give you gifts and they do. I got tons of cool stuff.
