How To Make an Improved Crouch/Crawl Animation?

Hello, I was recently watching one of AlvinBlox's tutorials (How to Make a Piggy Game) and I got to the part where he showed us how to make a crouching animation. Everything worked exactly how he scripted it, but I was wondering how I could improve it. There is a place for only one animation ID, the idle crouch animation, but no crawling animation. I was wondering if there was a way to add a crawling animation onto the script. Here's the script:

-- Piggy "Anims" Script
-- Description: Handles animations for crouching and turning the crouch GUI on/off at different times.

local player = game.Players.LocalPlayer

local userInputService = game:GetService("UserInputService")

local animationID = "rbxassetid://181091341"

local animPlaying = false

function crouch()
	if player:FindFirstChild("Contestant") then
		if animPlaying == false then
			local animObj = Instance.new("Animation")
			animObj.AnimationId = animationID
			local loadedAnim = player.Character.Humanoid:LoadAnimation(animObj)
			loadedAnim:Play()
			player.Character.Humanoid.WalkSpeed = 10
			animPlaying = true
			script.Parent.Crouch.ImageColor3 = Color3.fromRGB(26, 144, 255)
			script.Parent.Crouch.TextLabel.BackgroundColor3 = Color3.fromRGB(26, 144, 255)
			print("Playing")
		else
			print("Stopping")
			for i , v in pairs(player.Character.Humanoid:GetPlayingAnimationTracks()) do
				v:Stop()
			end
			player.Character.Humanoid.WalkSpeed = 16
			animPlaying = false
			script.Parent.Crouch.ImageColor3 = Color3.fromRGB(255,255,255)
			script.Parent.Crouch.TextLabel.BackgroundColor3 = Color3.fromRGB(255,255,255)
		end
	end
end

userInputService.InputBegan:Connect(function(input,gpe)
	if input.KeyCode == Enum.KeyCode.LeftControl then
		print("Correct input")
		crouch()
	end
end)

script.Parent.Crouch.MouseButton1Click:Connect(function()
	crouch()
end)

game.ReplicatedStorage.ToggleCrouch.OnClientEvent:Connect(function(visiblity)
	script.Parent.Crouch.Visible = visiblity
	for i , v in pairs(player.Character.Humanoid:GetPlayingAnimationTracks()) do
		v:Stop()
	end
	player.Character.Humanoid.WalkSpeed = 16
	animPlaying = false
	script.Parent.Crouch.ImageColor3 = Color3.fromRGB(255,255,255)
	script.Parent.Crouch.TextLabel.BackgroundColor3 = Color3.fromRGB(255,255,255)
end)

Thanks in advance!

If you get the plugins Build Rig and Animation Editor you can use those. It is pretty easy to learn how to use them.

Hey! what you need to do is you need to click the 3 dots then click set animation priority, then you set it to action. Hope I helped!
