any idea why my idle animation doesnt go back to the original one?

So I have a Animate localscript in Startercharacterscripts with some custom animations, and I have a tool/ability that changes your animations. I made 2 folders in ReplicatedStorage that each have 1 animate script, 1 which has the original one (the one in startercharacterscripts), and the other which has different animations which the tool uses. When I activate the tool the animations work fine, but when I disable the tool the animations don't change back, please help! heres the server script inside the tool:

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 Tail = game.ReplicatedStorage.CloakTails.FourTail:Clone()

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

plr.Character.Head.face:Destroy()

end)

plr.Character:FindFirstChild("FourTail"):Destroy()

plr.Character.Humanoid.MaxHealth = plr.Character.Humanoid.MaxHealth - HPBuff 
plr.Character.Humanoid.Health = plr.Character.Humanoid.Health - HPBuff

They don't change back because you destroyed the original animation.

plr.Character.Animate:Destroy()

You should instead just clone the original animation script to somewhere in your character (not directly in it, I'd say a folder or something).

And then you can run a unequipped connection to give the original animations back to your character with:

plr.Character["Some Folder"].Animate.Parent = plr.Character

You can then destroy the other animations other than the original one inside the unequipped connection.
