O.K., I'm sorry it took so long.
Green got to the only city he could think of even remotely linked to mermaids, Cerulean. 'Blue got pretty lazy with this riddle' he thought, as he turned to head north. The nugget bridge was already within sight, and it was getting late, Green could see the light from bill's light house in the distance.
On the north side of the bridge Green had no clue where to check for the next note, it was slowing him down and with Blue already knowing he was following her he didn't want to fall to far behind. He was wandering through the trees, trying not to get lost but that wasn't easy, seeing as each tree was the same as the last. Every once in a while he looked up to see the light of light house, and used that to guide him.
After about twenty minutes Green found himself out of the trees, and in front of the tower he'd been using to find his way. No note yet, so he went in.
Near the main entrance of the building Bill, the pokémon researcher lay face planted to a desk, snoring slightly. Green decided not to wake him up unless there was no note, or other clue. The trainer started his assent up the stairs of the structure thinking 'how hard would it be to install an elevator?'
He reached the top at a bit passed nine thirty, and saw the piece of paper that had been left the waiting for him on a desk to one side of the room. Most of the room was take by the slowly rotating light that gives a light house it's name. He ran forward to check the note, and found a small glass lens hanging next to it. He decided to ignore the lens for now, and read the note 'If ya made it this far nice job. I guess you just really wanna find me hmmmmm ; )' "very funny" Green sarcastically remarked before continuing 'well I hope you got here fast 'cause to find the last note you gotta see where the sunlight focuses to through the lens at eight o'clock, sorry no points if your late.'
"Damn it!" Green's said, accompanied by the sound made when fist meets table. He was over an hour and a half late. But he wasn't going to give up here, he just had to find out why she was trying to lure him in. He turned the note over and grabbed a pen form the desk. He then used what he knew about the area to determine where the sun would have been at eight o'clock. Now to reflect the light. "Go syzor! Metal claw", the trainer commanded. A new creature stood next to him now, a syzor, with one claw now coated in reflective metal. After some brief instructions the syzor backed toward the lens and lifted it's reflective claw near it, while it's master was busy holding the lighthouse light in place.
"A bit to the right syzor" commanded Green. Syzor obeyed, and let the light reflect off it's claw into the lens, and a beam of light shot from the lens, out the tower, and across the ocean into the hoenn region. "did she have to make this one so difficult?" said the trainer as he picked up his things and began to make his way toward the far away land.
