The situation in Pokémon Tower is grave indeed, but with the Silph Scope, you should be able to dig up whatever is causing all the trouble. You don't have to do anything special with the scope, but just make sure you have it with you when you enter the tower. The Silph Scope automatically identifies ghosts and makes it possible to engage them in combat.
Into the Tower
With the Silph Scope in your hot little hands, it's time to head back to Pokémon Tower and figure out what the heck is going on. The quickest path is to go back to Route #7, hand the guard a frosty beverage to end the baffling "Thirsty Guard" crisis, and then cut through Saffron City on your way East to Lavender Town. On your way through Saffron City, you might just want to stop in at the Poké Mart and grab a Max Repel. The Repel is for the Tower, where you'll be assaulted by Gastlys, Gastlys, an occasional Haunter, and more Gastlys.
Not this guy again...
When your rival gets in your way on the second floor, he'll pick a fight as usual.
If you're playing the Red or Blue cartridge, he might have an alternate lineup (a level 25 Pidgeotto, a level 23 Gyarados/Exeggcute/Growlithe, a level 22 Growlithe/Gyarados/Exeggcute, a level 20 Kadabra, and the Pokémon he chose at the beginning of the game). Gyarados is absent if you select Charmander, and your rival will have a level 23 Growlithe and a level 22 Exeggcute in his lineup. Exeggcute is absent if you select Squirtle, and your rival will have a level 23 Gyarados and a level 22 Growlithe in his lineup. Growlithe is absent if you select Bulbasaur, and your rival will have a level 23 Exeggcute and a level 22 Gyarados in his lineup.
In the Yellow game, he'll be a little more formidable. Besides his Fearow, Shellder, Magnemite and/or Vulpix and Sandshrew, your rival will also use his Eevee, which he will soon evolve into a Flareon, Vaporeon or Jolteon. Shellder is absent if your rival is going to evolve Eevee into Vaporeon, and your rival will have a level 23 Vulpix and a level 22 Magnemite in his lineup. Magnemite is absent if your rival is going to evolve Eevee into Jolteon, and your rival will have a level 23 Shellder and a level 22 Vulpix in his lineup. Vulpix is absent if your rival is going to evolve Eevee into Flareon, and your rival will have a level 23 Magnemite and a level 22 Shellder in his lineup.
Ghosts are completely invulnerable to Normal and Fighting moves, so many of your Pokémon's attacks will be useless here. Because of the Ghosts' second type, Poison, they are weak to Psychic and Ground-type moves. Anything that can use Dig, especially a speedy one like Diglett, can pretty much get an instant K.O. Pokémon like Kadabra and Drowzee are very powerful too. If you don't want to deal with lots of random encounters, just pop open the Max Repel... After you catch a Gastly for yourself.
A chance for rest
The leader of the Channelers has broken free of the dark power that held her, and created a reusable healing zone on the 5th floor. Make sure you heal and save while you have the opportunity, since there are a number of surprises ahead. Move one step forward and three steps down from the stairs to snag a hidden Elixir.
The first surprise is at the stairway to the top floor, where the Ghost that you needed the Silph Scope for finally reveals itself as a level 30 Marowak. Make sure you have some strong, non-Psychic Pokémon for this fight (or just use a Poké Doll)! You cannot catch this Pokémon, as it will dodge any Poké Ball you throw its way, even a Master Ball!

At the top
More non-Gastly foes await on the top floor. Red/Blue players have to go through three Rocket guards, while Yellow players just have to deal with a single visit from Jessie and James, the pair of losers that's been trailing them all along.
After you've bested those foes, you'll find the missing Mr. Fuji. He'll thank you for your efforts with a gift of a Poké Flute, which you can use to awaken any sleeping Pokémon, and which finally makes that Rest skill useful.
You can also use it to wake up that sleeping Snorlax that was blocking the passage between Route #11 outside of Vermilion City and Route #12 south of Lavender Town. But first, let's pay a visit to Saffron City.
|#92 Gastly||#104 Cubone|
They're weak to Psychic and Ground attacks, but their immunities more than make up for that minor inconvenience. Built-in attack Night Shade does damage equal to Gastly's level regardless of type, and Lick paralyzes foes.
The decent Ground-type skill Bone Club comes built in, but better attacks like Bonemerang and Thrash (which does heavy damage, but confuses Cubone) don't come until higher levels. Cubone is better in Yellow, since he learns Headbutt at level 18!
