How do you catch mew in poke Mon heart gold?

You can't catch Mew in Pokémon HeartGold. Mew is not available in that game.

Here are the ways Mew has been available in other Pokémon games:

* Events: Mew has been given out at special events, sometimes through special codes or Wi-Fi distributions.

* Special Versions: Some special editions of Pokémon games have included Mew as a pre-loaded Pokémon.

* Glitches: While not an official method, there have been glitches in certain games that allowed players to access Mew.

However, if you're looking for a rare Pokémon to catch in HeartGold, you can try your luck with:

* Ditto: Found in the Ilex Forest

* Unown: Found in various locations, each with a different letter form

* Shiny Pokémon: While any Pokémon can be Shiny, some are rarer than others.

Keep in mind that capturing any of these Pokémon requires patience and a bit of luck!
