The only to get there is to activate Darkrai event.. There's a house at canalave which you can't get in, unless you activate it. You will have to sleep on the bed and you will be transported to New Moon Island.. There you will encounter a wild Darkrai.
By right.....It's just a typical shiny pokemon... They just make the entire storyline dramatic, or perhaps to tell you that shiny exist in the game..
Nope.. Legendarys can't breed.. If it's possible, there wouldn't anymore Pokemon game lineups.. Everybody will start to give away their legendarys..
The honey tree at Valley Windworks have a high chance to get Munchlax
You need the Adamant and Lustrous Orbs in Mt. Coronet. After getting 'em, talk to the guy in the large house in Celestic Town. Head back to Spear Pillar and you will see a blue portal (Dialga). After capturing, exit the area and head back in and you will see a pink portal (Palkia).
I have a shiny bidoof or however you spell it.. -.-
Mt. Coronet -> Route 216 -> Route 217 -> Acuity Lakefront. Whichever entrance you take to enter Mt. Coronet, you need HM04 (Strength) to proceed north to Lake Acuity
