Can I use ButtonDown without a HopperBin?

local Player = game.Players.LocalPlayer
local bin = script.Parent 
bin.Selected:connect(function(Mouse)
	Mouse.Button1Down:connect(function()
	local TestAttack = Instance.new("Animation")
TestAttack.AnimationId = "http://www.roblox.com/Asset?ID=277328828"
local animTrack = Player.Character.Humanoid:LoadAnimation(TestAttack)
animTrack:Play()

	end)
end)
	

Is it possible to use this without a HopperBin?
