Player = script.Parent.Parent.Parent mouse = Player:GetMouse() run = game:GetService("RunService") LeftShoulder = Player.Character.Torso["Left Shoulder"] RightShoulder = Player.Character.Torso["Right Shoulder"] waittime = 4 bin = script.Parent me = script.Parent.Parent.Parent enabled = true function onKeyDown(key) if not enabled then return end if key == "f" then enabled = false Run = game:GetService("RunService") game:GetService("Chat"):Chat(me.Character.Head, "Hehe") wait(1) game:GetService("Chat"):Chat(me.Character.Head, "Sharingan!") Player.Character.Head.face:remove() c = Instance.new("Decal") c.Face = "Front" c.Texture = "http://www.roblox.com/asset/?id=145094083" c.Parent = Player.Character.Head c.Name = 'face' Player.Character.Humanoid.MaxHealth = Player.Character.Humanoid.MaxHealth + 30 Player.Character.Humanoid.WalkSpeed = Player.Character.Humanoid.WalkSpeed + 2 wait(240) Player.Character.Head.face:remove() Player.Character.Humanoid.MaxHealth = Player.Character.Humanoid.MaxHealth - 30

Player.Character.Humanoid.WalkSpeed = Player.Character.Humanoid.WalkSpeed - 2 end end mouse.KeyDown:connect(onKeyDown)
