Goto six isle dotted hole. cut down door. follow hole pattern up, left, right, down. Press A facing sapphire. Man will appear take Sapphire and tell you 2nd password.
The old answer was nonsense i have a better answer.ill tell you what you have to do for dotted hole.1. go to ice cave on island 4 and find lorelei (the first elite 4 member).2. now the man wont be in front of the entrance of dotted hole on island 6.3. go through the door by using cut and then go down the first hole.4. Now the hole sequence is: Up, Left, Right, Down.5. then a geek will take the Sapphire and tells you the second code: Yes, nah, CHANSEY.Ps: the 2 codes are: 1- Goldeen rod ness. 2- Yes, nah, CHANSEY.6. Finally, go to rocket werehouse on island 5 and do the things there.7. now you reach the geek who has the Sapphire and he gives you it.8. Give celio the Sapphire and you're done with that.well that was the guide. -PokemonAnswerMaster-Oh and if you want mewtwo beat the elite 4 and do the ruby Sapphire thing for celio and cerulean cave will be open. =)Hope this helps.Go to four island and go in icefall cave find HM7 then use it to go up the waterfall then go to the ladder beat the rocket then talk to lorelei then leave and go to dotted hole the guy shouldn't be there now.
