Model is not going where its primary part is going???

local sound = Instance.new("Sound", script.Parent)
sound.SoundId = "rbxassetid://1858323537"
local meow = true
local tent = script.Parent:GetChildren()
local orginal = game.ServerStorage.Monster1
local copy = orginal:Clone()
local spawnspots = game.Workspace.SpawnArea:GetChildren()
local randomItem = spawnspots[math.random(1, #spawnspots )]


script.Parent.Humanoid2.HealthChanged:Connect(function(changer)
    if script.Parent.Humanoid2.Health <= 0 then
        if meow == true then
            meow = false
            sound:Play()
            wait(3)
            script.Parent:Remove()
            wait(3)
            meow = true
            copy.Parent = game.Workspace
            print(randomItem)
            copy.PrimaryPart.Position = Vector3.new(spawnspots.Position)
        end
    end
end)

so basically this is supposed to bring my model to one of the spawnspots, but it will only bring the primary part, and not the rest of the model. Do I need to weld it or is there something else I can do?
