How can I change the player's package when the player joins?

Like, In RangeMeludE's new game, You join and your package is changed to that villager. How can I do it? Here's what I got so far..

function onPlayerEntered(newPlayer)
	--Here is where I don't know how to change the package of the player.
end

game.Players.PlayerAdded:connect(onPlayerEntered)
