The Distortion world is only available in Pokemon Platinum
shadow lugia is not in Pokemon platinum
You should Know that.
No only in Pokemon platinum (coming in stord march 22 2009) no it is not possible to get into the reverse world in Pokemon pearl. It is is only in Pokemon platinum which comes out on march 22nd in the US
You need to fight Dialga and palkia where u fought them in dimond and pearl and then after u defeat them you get sucked into the reverse world.
(Pokemon Platinum Only) A portle to the Dostortion (Reverse) world.
Its in the room where Giratina is in which is turn back cave.
once you get so far in the game, an event similar to the ones in Pokemon Pearl and Diamond will happen, only with giratina and the Reverse world
You need to battle Girtina in the Reverse \World then you will be able to go to Sunnyshore
