In Pokeworld, you go to Aunt Bibby to find your pokemon's friendship level. She gives you a few words, and most players can figure out the connotation of that. However, she doesn't actually tell you their friendship level. Could you make it so in the message it gives you your pokemon's exact friendship level? If not, you could post a guide stating what range is meant when Aunt Bibby says a phrase about the friendship level of your pokemon.
Um.. u can always just stuff ur pokemon with berries until it says "Will have no effect" then garuntee ur poke is max happy.
Any berry will increase the pokemons happiness level, but will lower an ev stat(hover over the berry to see which stat it lowers)
