Player keeps playing the Idle Animation for a tool, even when unequipped. Why Is that?

So I am some-what bad at scripting, but I decided to use this script, the script will play the Idle animation however when unequipped the Idle animation will keep playing even though I use :Stop()

Script:

local Tool = script.Parent
local Animation = Tool.Idle

Tool.Equipped:Connect(function()
	local Character = Tool.Parent
	local Humanoid = Character.Humanoid
	
	local AnimationTrack = Humanoid:LoadAnimation(Animation)
	AnimationTrack:Play()
end)

Tool.Unequipped:Connect(function()
	AnimationTrack:Stop()
end)

This is a quick simple mistake. :Stop() actually doesn’t exist. Here’s an actual script that works!

Tool.Unequipped:Connect(function()
    AnimationTrack:Pause()
end)

Thanks!

1. Removing the local infront of the variable because of the scope.

2. Reversing the animation would be an option too. https://developer.roblox.com/en-us/api-reference/function/AnimationTrack/AdjustSpeed

AnimationTrack:AdjustSpeed(negative number to play it backwards)
