Unlocking Skull Doors
I'm not reallly sure if this is a cheat or a hint, but once you save Mick's navi from the navis of the undernet and your aloud in the undernet, get rushfood from a dark navi in I think it was the Shower comp in Sky Town, it costs 3000 zenny per rushfood I think, and go to the right of undernet 1 and find a dog bone icon like in the manual and press the A button and a dog will appear to become your bridge. Go until you see a dark navi saying "I dropped a memo with the password in...Some comp in Sky Town...". He's talking about the oxygen tanks in the place in the lockers where the guy from the admin fell out, but no need because the password for the gate ahead is 729. If you keep going you'll find a staircase. Go up it. There will be a dark navi there. He'll offer you WWW ID for 7000 zenny I think it is and if you buy it, it will be like the key fot the skull doors.
