---FIRST: be sure to not fight the youngster with a slowpoke on the road to bills house, otherwise known as rt. 25, he is the fourth trainer you encounter after crossing the bridge. he's standing above a female trainer facing north.
---SECOND: be sure also not to battle the gambler with 2 poliwags and a poliwhirl between saffron and lavender. he's standing right of the entrance to saffron city, facing north to the door of the underground path
---THIRD: Make sure you have a Pokémon that is capable of flying. On Rt 8, stand in front of the door of the Underground Path. save your game before continuing.
---FOURTH: Walk down one step and INSTANTLY PRESS START. If you do it correctly, the menu will pop up before the Gambler "sees" you. Use your flying Pokemon to fly to ceurelean.
---FIFTH: The Gambler will see you when you start to fly away. Once in Ceurelean, your start button will no longer work. Go north across the bridge and head east until you find the youngster mentioned above.
---SIXTH: Do not walk right up to him, doing so will lock up your game. get a few steps in front of him and let him walk up to you. defeat him, and your start button will work again. Fly back to Lavender.
---Seventh: Head west into Route 8. As soon as you enter the narrow path, the menu will appear on its own, press B to exit it, and from nowhere Mew will appear. He will be at Level 7 and its only attack will be Pound. you can save with no fear of glitches:)
Mew was originally found in Pokemon red and blue by using the Mew glitch.
blue mew is a shiny version of mew so you have to be very lucky to catch a shiny Pokemon let alone a shiny mew
In the game
Mew was a special event Pokemon that was distributed for Pokemon Red and Blue. Mew cannot be found in the wild without cheats or using glitches, which is still possible to obtain. Bulbapedia likely have a great summary about this Mew glitch in Pokemon Red and Blue.
The Pokemon that are in Pokemon blue are at least the first 149 Pokemon in the pokedex. I'm not sure about Mewtwo or Mew though
Mew i think i have a shiny one its blue :D
The only way to get Mew in Pokemon Red, Blue, and Yellow is via the Mew Glitch, which you can find on Bulbapedia.
(Action replay) You can also use the Mew glitch in Pokemon red or blue and then just trade up.

It can be caught in Pokemon blue/red/ and yellow.
Anything.
