Well i just hear that on pokemon platinum when you have all the badges talk to the
proffesor and he'll give you a poke radar and you will be able to "chain". To chain there
are differents types of grass. 1# grass is rustling. 2# small sparkles. 3# hugee sparkles.
1 and 2 are mostly commoon to happen with pokeradar but if there 3# its a big chance of
getting that pokemon shiny. If you chain 40 or more pokemon it's likely you will encounter
that pokemon shiny. But if your chain breaks by seeing a different type of pokemon you
will need to start all over again. Another way is for it to come natural, which is a
chance 1 out of 8,000 something. One more way is to have an action replay code(any pokemon
game) and it'll make every pokemon shiny. Even your pokemon team and pokemon in your pc.
To undo it, idk. I dunt hav one soo yea just meh knowledge.

Thanks i do have platinum but i lost it a few years ago after defeating the champion for
the 100 time in a row.

Hi there! Shiny Pichu's can be found in a Mystery Gift. But I know more about the
Spiky-Ear Pichu if you want to hear about that? The spiky-ear pichu is a special pokemon
that can only be caught in an event.
Instructions are written: if you send over the special pikachu coloured pichu, obtained
from an event or over wifi, a special feature will activate... *if you have inadvertantly
evolved this special pichu into pikachu or riachu, the event will still work* put the
special pichu in your party and head over to ilex forest where the event will take place.
Go past celebi's shrine in ilex forest to find a spiky-ear pichu. This pichu is caught at
level: 30 and will be holding a zap plate. Even though its a special pokemon there is a
draw back to the spiky-eared pichu. First, the pichu is unable to evolve into pikachu and
as such not into raichu. In addition to this, it is unable to be traded to other games.
After all the commotion take your spiky-ear pichu to professor elm for a surprise. Please
ask any questions if confused. Hope this helps,

So how do you get it through the mystery gift? Mystery gift never worked for me *sigh*

I've really wanted a pichu and thanks to you i can finally get one.

You can aobtain shinys through normal breeding however its the normal 1/8192 chance what
your describing here is the massuda method which deoending on your gen multiplys your
chances by 5-6 times (5 iif gen 4 6 if gen 5) of getting a shiny, which makes the process
of getting shinyys easier and better because you can breed for natures, ivs, and egg moves
