How do you get passed ghost in Pokemon LeafGreen haunted mansion?

You can't actually "get past" the Ghost in Pokemon LeafGreen's Haunted Mansion. The Ghost is a trainer you have to battle.

Here's how to defeat the Ghost:

* Use a Pokemon that is strong against Ghost-type Pokemon: Ghost-type Pokemon are weak to Ghost and Dark type attacks. If you have a Pokemon of these types, it will be very effective.

* Use a Pokemon with a high Special Attack stat: Ghost-type Pokemon are primarily weak to special attacks.

* Be careful of the Ghost's moves: The Ghost's most likely move will be Lick, which is a Ghost-type move. Be prepared for this!

Good luck defeating the Ghost!
