Pokemon Fire Red/ Leaf Green Lady Selphy Trick

First, to get to Lady Selphy, you need to get to her through Lost Cave. There are also some important items for filling your Pokedex in the cave.

Direction Keys: >= Right, <= Left, ^= Up, and v= Down.

Lady Selphy:>, ^, v, v, >, <, v, >, ^. Lady Selphy will challenge you to a match. She has two Lv.49 Persians, and if you go back to where she was, you will find a Silk Scarf. A Silk Scarf raises the power of any Normal type attack by 10%, making Tauros even better.

Lax Incense: >, v.

Max Revive: >, ^, v, v, >, >.

Rare Candy: >, ^, v, v, >, <, v, <.

Sea Incense: >, ^, v, ^.



Whatever you do, DO NOT SELL EITHER OF THE INCENSES! If you need more money, go to the Vermilion City Pokemon Center, and talk to the girl standing next to where you are when you're getting your Pokemon healed. She will give you a Vs. Seeker, which allows you to challenge any trainer you have battled before. It also shows trainers you haven't battled before with a red "!" above their heads. A trainer you have battled before will either have a blue X or a blue "!!" above their head. The incenses are used for getting two Hoenn Pokemon. Give a Wobbuffet the Lax Incense and breed it at Four Island to get a Wynaut, and a Marill/ Azumarill with the Sea Incense for an Azurill.

So then, go to the house at Resort Gorgeous that says "Selphy" on the mailbox. Talk to Lady Selphy, and she will ask to see a certain Pokemon. Save before you talk to her in case you don't have the Pokemon she wants to see. Then fly back to the Five Island Pokemon Center and get the Pokemon. She will always ask for a Pokemon in your Pokedex, whether you've caught it or not. If you show her the Pokemon she wants to see, she will give you an item you can't buy anywhere. What I've gotten from her so far is:
11 Luxury Balls.
3 Stardusts.
2 Nuggets.
2 Pearls.
2 Rare Candies.
1 Star Piece.
I believe that may be all of the kinds of items you can get from Lady Selphy. Also, I think the reason you may only find a few of the items in Lost Cave in other places is because Selphy must have dropped them while looking for a way out of the cave.
