Ever notice any messages in a Pokemon's pattern, or in it's Pokedex? For instance, if you take Regirock, Registeel, and Regice, place them from left to right in that order, Regirock's pattern of circles forms an "H", Registeel's pattern forms an "O", and Regice's pattern forms a sort of "T". That spells "HOT".
It's kinda funny. Anyway, any of you ever found any of these? There are quite a few in FireRed.
