Q&A for How to Get to Celadon City in Pokémon FireRed

To get past the Team Rocket hideout, you must defeat all the grunts and then defeat Giovanni. Once Giovanni is defeated, you will receive the Silph Scope, which allows you to save Mr. Fuji.

While a level 100 Tyranitar may not consistently obey you without the necessary Gym Badges, you can still use it in battle.

Upon entering Celadon City, head north to locate the large building commonly referred to as the hotel. To enter it, proceed to its left side and find the rear entrance. Once inside, go to the top floor, then head south and enter the room to find a Poké Ball.

To reach the fourth gym, travel south from Celadon City. You will find your path blocked by a tree, so use Cut to remove it. Afterward, proceed left and then up to enter the gym.

Head right and then slightly south; continue heading right until you spot a building that resembles an arcade. This is the Game Corner.

The entity you encountered is likely a Haunter. You can battle it and then choose to defeat, capture, or flee from it.
