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
