Items

Hidden items need the Itemfinder or a lucky press of A on the right tile.

Tips

• Interact with the statues to flip the barriers and open new paths; the same switch changes all floors.
• The Secret Key is on B1F and opens the door to Cinnabar Gym.
• Growlithe lives here and the Burglars use Fire-types, so Water attacks are handy.
• Items include TM14 Blizzard, TM22 SolarBeam, Full Restore, Max Potion and Rare Candy.
• Journals scattered around hint at the origins of Mewtwo.
