Hello, I just need two things if anyone has the time to help lol, I would like the code for the "whisper" verb (private message or PM) for my pokemon game

And I have a question, let's say you have a grass turf that covers the entire map, and you have a NEW grass turf that you would like to replace with the current one... Is there a way to replace the old grass turf with the new grass turf all at once? Because I can't use the full option because I have buildings, trees and other various objects on the map...
