Do you go to the old man in Pacifilog with a Wynaut Mirage Island?

It seems you're asking about a specific event in the Pokémon games. However, there is no "Wynaut Mirage Island" or an "old man in Pacifilog" mentioned in any official Pokémon game.

Could you please clarify what game you're referring to or provide more context?

Perhaps you're thinking of:

* A specific fan-made game or mod: If you're playing a modified version of Pokémon, the rules might be different.

* A specific event in the game: Are you referring to a specific event that happens at a certain point in the game?

* A specific location: Is there a specific location in the game you are thinking of?

Please provide more information so I can better assist you.
