The same way you find any shiny pokemon, either constantly run back and forth in grass that you want to encounter as a shiny, or constantly breed the pokemon until you hatch a shiny.
Get a action replay and and go to codejunkies
Keep walking around where you see Noctowl. Eventually, and VERY rarely, you will find a Shiny Noctowl. The PokeRadar helps, too. If the grass is shiny while using it, it's a shiny.
just run in the grass
Yup. He has a shiny Noctowl.
random event in the grass
it depends the game you have, but if you have pearl or probably any other pokemon game go to the pokedex and look for the pokemon if you find it click on it and go to the part of the map there it tells you if its found or not
Noctowl doesnt exist in Pokemon yellow, blue, or red
There is no easy way to find a shiny...There's a 1 in 1,500(or higher)that it'll be a shiny.The only 100% to get a shiny is to hack the game or cheat with Action Replay.You'll need the "Wild Pokemon Are Shiny Code" for the Action Replay.Action Replays are sold at video game stores and cost $20 to $25..at least that was the price when I bought mine.
Both! Noctowl appear in the grass and Hoothoot appear by headbutt.
I dont think you can.
The first official Shiny Pokémon that showed up in the Pokémon TV show that actually matches the Shiny colorization as shown in the games would be the Shiny Noctowl that Ash caught while in the Johto region.
Go to Pastroria City and there's a Safari there and you can find HootHoots and they commonly evolve. If you are on the way to Snowpoint City there are rare pokoemon with Noctowl itself. Hope this helps >_-
