I remember when the Version 4 first came out we got a LOT of questions about what the star mail was about.
Gotchi Points Bag =
If you get one star or two stars for this, you will win 400 points for a win in a game, the normal amount. Get three stars and you'll win 500.
Heart Icon =
Get one or two stars for this, you will probably not go up a friendship level on your next connection with a friend. Three stars and you have a good chance of your friendship level going up during the next connection with a friend.
Strong Man Icon =
Get one or two stars for this and it doesn't make any difference one way or another. Get three stars and you become a little less likely to become sick.
