There are such things as pokegods. To get them beat the Elite Four 30 times without talking to anyone in between the nurse in the pokecentre at Indigo Platue or what ever it is, and the riv . On the thirtith times Professer Oak will say "I'm getting tired of this" and he will let you walk around the hall of fame which leads to a new city where people will swap pokegods.

TRUE PIKABLUE CODE:PIKABLU-to get pikablu you must first get all 150 Pokemon(you can't have mew)Then get one Pokemon that has surf and one that has teleport.Next surf in the waters by the Unknown Dungeon.Teleport in different areas until you find a bottle.After you have the bottle go to where the bottle says Pikablu is.Next to him is a Mist stone that evolves Mew into Cyromew.(this takes many hours and is very hard to do).
