Pop-Up Images and Sounds?

easy

Put your ScaryPopup named 'ScaryPopup00' inside Lighting and the Scary sound inside lighting too but named 'ScarySong'

Put this script inside your part:

script.Parent.Touched:connect(function(p)
if (p.Parent:findFirstChild('Humanoid')~=nil) then --Finding out player
if p.Parent.Name~='Workspace' then --Security Check for Scary Game Parts
local Pl = game:service('Players'):GetPlayerFromCharacter(p.Parent)
if (Pl~=nil) then
local Prx = Pl.PlayerGui
if Prx~=nil then
--This is where we go
local Pop = game:service('Lighting'):WaitForChild('ScaryPopup00') -- The Popup
local Son = game:service('Lighting'):WaitForChild('ScarySong') -- The Song
Pop:Clone().Parent=Prx -- Making it appear in PlayerGui
Son:Clone().Parent=Prx
--BUT WHY PLAYERGUI!!!???
--PlayerGui cuz it's the only way to show stuff only for the player. Hope this helps you!
