You cannot get a Murkro in Pearl, it is a Diamond only pokemon. Some pokemons are exclusive to Diamond and others are to Pearl.
you can't
Look in a walkthrough guide. It WILL show you.
you have to have 2 or more pokemons and it has to be open. Its open in the day time
you gotta see all the sinnoh pokemons
You can't. The only way you can get a spiritomb in Pearl or Diamond is using the flute at the top of the tower.
I really don't think so
