I'm not exactly sure what this is, but I kinda want to get into the Blue Building... So... Any insight as to how this works?

Pet rating is the overall number of stats in HP, attack, defense, and speed added together, if I remember correctly. Just train your pets up. :)

Oh, Okay! Thank you so much~~ :) To show you my thanks, I have sent you something to show my gratitude for helping me! :)
