I fed mine 7 Mamook Pears so far and I got the message two times.
Wonder what I will get with that. Then again I exchanged 2 of my pears for 2 Valfruits with a FC member. There is nothing with that combo in the Google Doc so far, which is why I can't wait to see what I'll get with that xD
(Except the 7 Mamook's get me a color I like)
