Mouse is not a valid member of Vector3?

Very confused on why I'm getting this error, I'm trying to make a tool make a part from replicatedstorage clone to workspace when clicked on with it activated and then its cframe will be constantly moving forward in the spot your mouse clicks on, but for some reason I keep getting that error. Heres the script:

local Tool = script.Parent
local Cooldown = false
local CDTime = 65



Tool.RemoteEvent.OnServerEvent:Connect(function(Player, Mouse)
    if Cooldown then return end 

    spawn(function()
        Cooldown = true 
        wait(CDTime)
        Cooldown = false 
    end)

    local Mugetsu = game.ReplicatedStorage.Abilities.Shinigami.Parts.Mugetsu:Clone()
    Mugetsu.Size = Vector3.new(1.427, 44.539, 1.55)
    Mugetsu.Parent = game.Workspace
    local pos = Player.Character.Head.Position + CFrame.new(Player.Character.Head.Position,Mouse.p).lookVector * 1 
    Mugetsu.CFrame = CFrame.new(pos.Mouse.p)
    Mugetsu.CanCollide = false
    Mugetsu.Anchored = false
    Mugetsu:SetNetworkOwner(Player)
    local BodyVelocity = Instance.new("BodyVelocity",Mugetsu)
    BodyVelocity.Velocity = Mouse.lookVector * 200
    BodyVelocity.MaxForce = Vector3.new(1e8,1e8,1e8)
    game.Debris:AddItem(Mugetsu,3.5)

    Mugetsu.Touched:Connect(function(hit)
        if hit and not hit.Parent:FindFirstChild("Humanoid") and hit.CanCollide == true then 
            Mugetsu:Destroy()
        end
    end)

    Mugetsu.Touched:Connect(function(hit)
        if hit.Parent == Player.Character then return end
        if hit and hit.Parent:FindFirstChild("Humanoid") then 
            local EnemyHum = hit.Parent:FindFirstChild("Humanoid")
            EnemyHum:TakeDamage(100)
            Mugetsu:Destroy()

        end
    end)
end)    

Please help
