Pokémon Lab
The Pokémon Lab is a laboratory founded by Dr. Fuji. The only real reason to visit here, is to trade the fossil you chose at Mt. Moon and the Old Amber from the Science Museum at Pewter City, for a couple of Pokémon, otherwise unobtainable.
Room 1
In the first room of the Pokémon Lab, there are two people who will offer to trade Pokémon. The old man will offer his Electrode for a Raichu, and the girl will want to trade her Tangela for a Venonat.

There is also another in-game trade: Ponyta for Seel, just talk to the blond guy in green.

Pokémon Mansion
The Pokémon Mansion is a decrepit, burned-down mansion. It got its name because a famous Pokémon Researcher once lived there. Amongst the rubble and wreckage is information that the scientists who once worked there obtained a Mew and impregnated it with the genetically altered Mewtwo, who destroyed the Mansion in its escape.
To access the Cinnabar Gym, you have to enter the mansion and find the Secret Key to unlock the door of the Gym. The Pokémon Mansion has four different floors. Doors can be unlocked in the mansion by pressing switches hidden in Pokémon statues.
Floor 1
Unless you want to get the items, there's nothing to do here. Proceed to the second floor from the stairs at the end of the main hall. There can be lots of walking pokemon, so consider using super repellant or the cleanse tag.

Cinnabar Gym
The Cinnabar Gym is the official gym of Cinnabar Island. It specializes on Fire-type Pokémon. The Gym Leader is Blaine. If you defeat him, you'll receive the Volcano Badge.
The Cinnabar Gym is a high-tech affair featuring a series of sealed doors. You must answer trivia questions about various Pokémon to unseal the doors, do this by interacting with the machines connected to the walls. However, when you fail to answer a trivia question correctly, a battle with either a Burglar or Super Nerd results, an alternative to unsealing the doors. The questions are:
- "Pokémon Quiz! Get it right and the door opens to the next room! Get it wrong and face a trainer! If you want to conserve your Pokémon for the Gym Leader... Then get it right! Here we go! Caterpie evolves into Metapod?"
- Yes, Caterpie evolves into Metapod, then into Butterfree.
- "There are 9 certified Pokémon League Badges?"
- No, there are only 8.
- "Poliwag evolves 3 times?"
- No, he evolves only twice; first into Poliwhirl, then into Poliwrath.
- "Are thunder moves effective against ground element-type Pokémon?"
- No, it's the other way around.
- "Pokémon of the same kind and level are not identical?"
- Yes, they're not.
- "TM28 contains Tombstony?"
- No, it contains Dig.
Even if you answer the question right, you still have the option to challenge the Trainer.

Defeating Blaine
Now that you've acquired the Volcano Badge, Bill (of PC fame) will meet you outside the gym. He mentions that he's going to one of the Sevii Islands and wants you to come along. You'll most likely need to heal after the battle with Blaine, and you still have not tackled Route 21; just say "no" and Bill will wait at the Pokemon Center for you when you're ready. Finish up Route 21, and then make sure that you're well stocked on Ultra balls - Moltres is ahead. But before you can get your hands on the Legendary Bird, there will be a few side quests for you to finish at the Sevii Islands.
