This office maze can be really confusing when you don't know where you're going. There are tons of teleporters that take you places -- and guess what, most of them are completely superfluous. All you need to do is take the elevator up to the fifth floor (you'll need to go the warp spot, then head back to 5F to get to it) and grab the Card Key in the narrow corridor in the southern part of the room. Now you can open every locked door in the building, so you don't need to try and warp around too much.
Rival Battle
Head to the third floor. Open the locked door and take the teleporter next to the table. You will now fight your arch nemesis, Gary. He's got the following Pokémon: Pidgeot (37), Growlithe (37), Exeggcute (35), Alakazam (35), as well as his trusty starting Pokémon at level 40.

Silph Company
By the way, you can heal your Pokémon at any time by going to the 9th floor and talking to woman in the southwest corner of the building. If your Pokémon are healthy enough for the final showdown, continue on from Gary's position to face the following trainers:
- Team Rocket Grunt
- Cubone (32)
- Marowak (32)
- Drowzee (32)
- Boss Giovanni
- Nidorino (37)
- Kangaskhan (35)
- Rhyhorn (37)
- Nidoqueen (41)
Beat Giovanni to get your hands on the valuable Master Ball. Store this gem away for later use.
There is no use in listing all the trainers in this building as you're likely to take your own route through here. After you have beaten Giovanni, you can now explore the building without getting attacked and safely retrieve all the items scattered about. Here's a look at what's where:
- 2nd Floor: Thunder Wave
- 3rd Floor: Hyper Potion
- 4th Floor: Full Heal, Max Revive, Escape Rope, TM41 (Torment)
- 5th Floor: Protein, TM01 (Focus Punch)
- 6th Floor: HP Up, X Special
- 7th Floor: TM08 (Bulk Up), Calcium
- 8th Floor: Iron
- 10th Floor: Carbos, Rare Candy, Ultra Ball
- 11th Floor: Zinc
Get Lapras
Be sure to pay a visit to the Silph employee on the 7th Floor, in the same room where you fought Gary. He will give you a rare Level 15 Lapras as a reward.
Get TM31 (Mimic)
Once you have liberated Silph Co., you can enter the house in the northwest. Give the Poké Doll you bought in Celadon City to the cookie girl upstairs and she'll give you TM31 (Mimic).
