getting a chimecho

go to mt.pyre in the ocean by the safari zone, then goto the top of the moutain there should be grass patches in the upper left and right it will take a while to find one good luck.

getting a shedinja

catch a nincada in the grass on the right of rustburo city easy way-if your enough through the game you can just chuck an ultra ball at it other wise just catch it the old way. leave room in your party then when nincada evolves at level 20 if you left room a shedinja will be in the empty spot of your party it will have the same moves as your ninjask it will have 1 hit point and its poke power is "wonder guard" only super effective moves hurt it.

catching kyogre

use a pokemon like vigoroth or slaking lv.35-50 or a pokemon that has a move that puts pokemon asleep and has alot of hit points for slaking use yawn and attack him with one of your medium strength attack when hes asleep throw any kind of catching system i caught him with a poke ball

1 word luck.
