Sound not playing after being cloned?

I have made a script that will turn any block into a teletubby, then make them sing the teletubby song, but sadly, they WON'T FRICKING SING (sry 'bout that...)!

Here is my script:

game.ContentProvider:Preload("http://www.roblox.com/asset/?id=275347097")

game.ContentProvider:Preload("rbxassetid://183730399")

local colors = {
    "Br. yellowish green",
    "Bright yellow",
    "Bright red",
    "Royal purple"
}

script.Parent["Tubbytronic Superdome"].MainDome.Sound:Play()

math.randomseed(tick())
script.Parent.Enter.Touched:connect(function(hit)
    if hit:FindFirstChild("Cash") then
        hit.Cash.Value = math.floor(hit.Cash.Value ^ 2)
        local parentvalue = Instance.new("ObjectValue",script)
        parentvalue.Value = hit.Parent
        hit.Parent = nil
        script.Face:Clone().Parent = hit
        hit.BrickColor = BrickColor.new(colors[math.random(1,#colors)])
        local antenna = script:FindFirstChild(tostring(hit.BrickColor)):Clone()
        antenna.Parent = hit
        for i,v in pairs (antenna:GetChildren()) do
            v.Anchored = false
            v.CFrame = CFrame.new(v.CFrame.X, v.CFrame.Y + hit.Size.Y, v.CFrame.Z)
            local weld = Instance.new("Weld", v)
            weld.Part0 = hit
            weld.Part1 = v
            weld.C1 = CFrame.new(0, (-hit.Size.Y/4)*3, 0) * CFrame.Angles(0,math.pi/2,0)
            v.Transparency = 0
        end

        ----=== Main Sound Part ===----

        local sound = script.Sound:Clone()
        sound.Parent = hit
        sound:Play()
        sound.TimePosition = math.random(0,(sound.TimeLength - 0.6)*10000)/10000
        sound.Pitch = math.random(500,1500)/1000

        ----===                           ===----

        hit.Parent = parentvalue.Value
        parentvalue:Destroy()
        hit.CFrame = script.Parent.Leave.CFrame
        for i,v in pairs (script.Parent.Windmill[" Wind"].Union:GetChildren()) do
            v.Enabled = true
        end
        local scropt = script.TubbyScript:Clone()
        scropt.Parent = hit
        scropt.Disabled = false
        wait(0.1)
        for i,v in pairs (script.Parent.Windmill[" Wind"].Union:GetChildren()) do
            v.Enabled = false
        end
        wait(0.9)
        hit.Parent = parentvalue.Value
        parentvalue:Destroy()
        hit.CFrame = script.Parent.Leave.CFrame
    end
end)

and also: There is no output

Edit: Added whole script
