How would i morph players every 60 seconds?

I am making horror game and I need to know this. So far this is all I have:

plr = game.Players:GetPlayers()
local el = game.Workspace.el
local elchanece = math.random(1,9)
if elchanece then
	
	
end
	
	

while wait(60) do
--get players
--morph all players
end
