Between 1-4 Minutes.
1 out of 8,000 chances you will see a shiny if it takes 8,000 chances for you to actually see a shiny Pokemon it will take you a dedicated 120 hours.
Save in front of Giritina and battle it. if it isn't a shiny, turn off the ds and try again. It will take a long time.
Well, your chances of finding a wild shiny pokemon are 1 in 8192 sooo to answer your question... a VERY VERY long time.
I recommend just mining to get it that's what i did it doesnt take long to find 1. hope this helped ! :)
On Heart Gold Pikachu is found in Viridian Forest and on a few other poke walker zones
Getting a shiny Pokemon is dependent on luck. The chances of encountering a shiny Pokemon is 1/8192, so it may take a long time to get a shiny Abra.
First go to Lake Verity. Use a super rod while surfing until you find the a red gyarados and try to catch it [it will take a long time to find it]. Then it will be holding an item, take it and it will be a dragonscale. Wrong: why? 1. red gyarados is shiny gyarados: to find a shiny you have 1/2000 chance. . not true. Horsea holds it
You can get a shiny Squirtle. The most reliable way to get a shiny Squirtle is to repeatedly hatch Squirtle eggs. This process will take a long time however and could take hundreds and hundreds of eggs.
There is no specific amount of time you need to spend to get a shiny. The time it takes is, like shinys, random.
Just keep searching for them. Any Pokemon can be shiny but there's only a 0.0122% chance of finding one. It will take a long time to find one; keep trying though, and good luck!
Unless you cheat to make a shiny Mudkip, the shiny appearance rate is 1 in 8192. You will be restarting the game for quite a while if you are determined to obtain a shiny Mudkip as your starter.
Either cheat... OR you can use the pokeradar and build up a really long chain. Eventually, this will find you a shiny pokemon. OR you can wander around and take the tiny chance that you will randomly encounter a shiny pokemon. OR you can slightly increase these odds by breeding different nationality pokemon, the baby one will be slightly more likely to be shiny.
