So I have a tool that adds a accessory to the player and changes their clothes, it also changes their idle animation. But how can I change the players running animation until I click again with the tool selected to remove all these features? script:

local Tool = script.Parent
local Cooldown = false
local CDTime = 6 
local HPBuff = 50
local WalkSpeedBuff = 15 

Tool.OpenEvent.OnServerEvent:Connect(function(plr)
if Cooldown then return end 

spawn(function()
	plr.Character:FindFirstChild("Pants"):Destroy()
	plr.Character:FindFirstChild("Shirt"):Destroy()	
	Cooldown = true
	wait(CDTime)
	Cooldown = false 
end)

plr.Character.Humanoid.WalkSpeed = plr.Character.Humanoid.WalkSpeed + WalkSpeedBuff
	
local pants = Instance.new('Pants', plr.Character)
pants.Name = 'Pants'
local shirt = Instance.new('Shirt', plr.Character)
shirt.Name = 'Shirt'
shirt.ShirtTemplate = "rbxassetid://2382909"
pants.PantsTemplate = "rbxassetid://272224987"	
plr.Character["Body Colors"].HeadColor = BrickColor.new("Crimson")	

Tool.Sound:Play()
local animationTrack = plr.Character.Humanoid:LoadAnimation(Tool.Animation)
animationTrack:Play()  --this is what plays the idle animation	
local Tail = game.ReplicatedStorage.CloakTails.FourTail:Clone()
Tail.Anchored = false 
Tail.CanCollide = false 
Tail.Parent = plr.Character
local Weld = Instance.new("Weld",Tail)
Weld.Part0 = plr.Character.LowerTorso
Weld.C0 = CFrame.new(0.09, 0, 2.69) * CFrame.fromEulerAnglesXYZ(0,179,0) 
Weld.Part1 = Tail	
_G.OriginalEyesTexture = plr.Character.Head.face.Texture
plr.Character.Head.face:Destroy()	
local Eyes = Instance.new("Decal")
Eyes.Texture = "rbxassetid://5719197948"
Eyes.Name = "face"
Eyes.Parent = plr.Character.Head	
plr.Character.Humanoid.MaxHealth = plr.Character.Humanoid.MaxHealth + HPBuff 
plr.Character.Humanoid.Health = plr.Character.Humanoid.Health + HPBuff
local Aura1 = game.ReplicatedStorage.JinCloakOneTailParticle:Clone()
Aura1.Parent = plr.Character.HumanoidRootPart
local Aura3 = game.ReplicatedStorage.JinCloakOneTailParticle:Clone()
Aura3.Parent = plr.Character.Head
local Aura5 = game.ReplicatedStorage.JinCloakOneTailParticle:Clone()
Aura5.Parent = plr.Character["Right Arm"]
local Aura7 = game.ReplicatedStorage.JinCloakOneTailParticle:Clone()
Aura7.Parent = plr.Character["Left Arm"]
local Aura9 = game.ReplicatedStorage.JinCloakOneTailParticle:Clone()
Aura9.Parent = plr.Character["Left Leg"]
local Aura11 = game.ReplicatedStorage.JinCloakOneTailParticle:Clone()
Aura11.Parent = plr.Character["Right Leg"]

end)

Tool.CloseEvent.OnServerEvent:Connect(function(plr)
	
plr.Character:FindFirstChild("FourTail"):Destroy()	

plr.Character.Humanoid.MaxHealth = plr.Character.Humanoid.MaxHealth - HPBuff 
plr.Character.Humanoid.Health = plr.Character.Humanoid.Health - HPBuff
plr.Character.Humanoid.WalkSpeed = plr.Character.Humanoid.WalkSpeed - WalkSpeedBuff
	
plr.Character:FindFirstChild("Pants"):Destroy()
plr.Character:FindFirstChild("Shirt"):Destroy()
plr.Character.Head.face:Destroy()	
	
local pants = Instance.new('Pants', plr.Character)
pants.Name = 'Pants'
local shirt = Instance.new('Shirt', plr.Character)
shirt.Name = 'Shirt'
shirt.ShirtTemplate = "rbxassetid://413009924"
pants.PantsTemplate = "rbxassetid://769453213"
	
local Eyes = Instance.new("Decal")
Eyes.Texture = "rbxassetid://5124465323"
Eyes.Name = "face"
Eyes.Parent = plr.Character.Head
	
plr.Character["Body Colors"].HeadColor = BrickColor.new ("Light orange")	

plr.Character.HumanoidRootPart.JinCloakOneTailParticle:Destroy()
plr.Character.Head.JinCloakOneTailParticle:Destroy()
plr.Character["Right Arm"].JinCloakOneTailParticle:Destroy()
plr.Character["Left Arm"].JinCloakOneTailParticle:Destroy()
plr.Character["Left Leg"].JinCloakOneTailParticle:Destroy()
plr.Character["Right Leg"].JinCloakOneTailParticle:Destroy()	
	
end)

This also goes in a server script
