How to get the arora ticket in Pokemon FireRed?

You can't actually get an "Arora ticket" in Pokémon FireRed. It's likely you're thinking of the "Seafoam Island Ticket", which is essential for accessing the island in the game. Here's how you can obtain it:

1. Defeat the Elite Four and become the Champion: This unlocks the post-game content, including access to Seafoam Island.

2. Head to the "Seafoam Island Ticket Lady" in the northeast corner of Cinnabar Island: You can find her in the house near the Pokemon Center.

3. Speak to the "Seafoam Island Ticket Lady": She will offer you the Seafoam Island ticket in exchange for the Kanto Pokédex.

Important Notes:

* Kanto Pokédex: You need to have caught at least 150 different Pokémon in the Kanto region to complete the Pokédex.

* Seafoam Island: This island is a post-game location and is only accessible after you become the Champion.

Once you have the ticket, you can show it to the guard at the entrance of Seafoam Island and enter.
