How do i make a character do an animation which changes their clothes and adds accessories to their avatar when something is said in chat? Also, when they’ve done that, they can say something else to return to their avatar form, for example:

“spots on” transforms them,
“spots off” detransforms them.

I think you should use Player | Roblox Creator Documentation and Animator | Roblox Creator Documentation and AnimationTrack | Roblox Creator Documentation and Humanoid | Roblox Creator Documentation and Instance.new

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
	player.Chatted:Connect(function(message)
		if message == "hello" then -- put here the message that the player has to say to play the animation
			local Humanoid = player.Character:FindFirstChildOfClass("Humanoid")
			if Humanoid then
				for _, object in pairs(player.Character:GetChildren()) do
					if object:IsA("Clothing") or object:IsA("ShirtGraphic") or object:IsA("Accessory") then
						object:Destroy()
					end
				end
				Humanoid:AddAccessory(game.ServerStorage.Accessory:Clone()) -- put your accessory here
				local Shirt = Instance.new("Shirt", player.Character)
				Shirt.ShirtTemplate = "" -- put your shirt template here
				local Pants = Instance.new("Pants", player.Character)
				Pants.PantsTemplate = "" -- put your pants template here
				local Animator = Humanoid:FindFirstChildOfClass("Animator")
				if Animator then
					local animationTrack = Animator:LoadAnimation(script.Animation) -- put your animation here
					animationTrack:Play()
				end
			end
		end
	end)
end)
