How can the annoying orange talk?

Answer 1

The creator Daneboe films himself talking in front of the camera with green paste around his mouth.

When he edits it, he uses the software to remove the green from the footage just leaving the mouth. He then tracks the mouth footage onto the orange, this is so his mouth stays still on the orange.

If this is not the correct answer.... It must be because of magic!

Hope that helps.
