Appendix:Yellow walkthrough/Section 7: Difference between revisions

[[Pokémon Tower]], where departed Pokémon are laid to rest, appears to be the source of the town's problems. Having a connection to the spirit world, most wild Pokémon found inside are {{type|Ghost}}s. {{ga|Blue|Your rival}} is waiting for you on the tower's second floor, but you can put that battle off until later. Beyond the second floor, you'll start encountering [[Ghost (literal)|actual ghosts]] and possessed {{tc|Channeler}}s, but without a {{DL|List of key items in Generation I|Silph Scope}}, you can't reach the tower's top floor.

Most [[Ghost (literal)|ghosts]] you'll encounter inside the tower are actually Pokémon in disguise, like {{p|Gastly}}, {{p|Haunter}}, and {{p|Cubone}}. Once you have the Silph Scope in your possession, it will reveal them as the Pokémon that they are, and you'll be able to battle or capture them. Gastly and Haunter are two of the only three {{type|Ghost}}s in the game (the third being {{p|Gengar}}), so it's worthwhile to track them down. There is one restless spirit in the tower, but since you can't do anything but run from it, it's best to ignore it for now. There are rumors of a Silph Scope prototype in [[Celadon City]], so it's time to head west.
