Key Items are those that are crucial to progressing in the game (or just special :P). You might find some spoilers in here because of this. Obviously, you can not toss them away. The Blue Orb can only be obtained in the Sapphire version, while it still exists in Ruby. Ruby players receive the Red Orb, and can only watch as Team Magma makes off with the Red Orb
