Please use code blocks correctly (

-- test

) And don't use Humanoid:LoadAnimation, use Humanoid.Animator:LoadAnimation I don't really understand but you could use: (Remove the --[[]] if you aren't trying to remove the function.)

player.Backpack.ChildRemoved:Connect(function(child)
	local anim = ANIM - your animation to remove
	local toolName = TOOLNAME -- your tool name, ex. if it was "Bat" then put "Bat".
	if child.Name == toolName then
		anim:Stop()
	end
end
--[[
(if you want to remove the connection or remove the function)
local connection = player.Backpack.ChildRemoved:Connect(function(child)
	local anim = ANIM - your animation to remove
	local toolName = TOOLNAME -- your tool name, ex. if it was "Bat" then put "Bat".
	if child.Name == toolName then
		anim:Stop()
	end
end
if [condition] then
	connection:Disconnection()
end
