I love this idea. \o/ Watering cans for Sprouts, it's adorable omg.

There could always be a different symbol too. But isn't one of the big draws the rewards/achievements from mentor roulette? (not a mentor, I don't actually know much about it lol). Not sure if an icon change will get rid of those people, unfortunately. Maybe take away the rewards so only people who actually want to help are using it. :P Of course we'll have 80% less mentors, but that's not necessarily a bad thing LOL.
