What the snitch said when harry put on his mouth Harry Potter and deathly hollows?

You're likely referring to a scene in Harry Potter and the Deathly Hallows (the book, not the movie) where Harry puts on the Resurrection Stone.

The Snitch doesn't actually speak in this scene. It's a moment of deep emotional significance as Harry uses the Resurrection Stone to see his loved ones again.

The Golden Snitch itself is not involved in this scene.

Do you have any other details about the scene you're remembering? Maybe that will help clarify what you're looking for!
