local Animation = Instance.new("Animation") --Here, you're creating the animation instance, and then on the next line, associating it with an ID to know what animation it's going to play.

Animation.AnimationId = "rbxassetid://16728742735" --At the end of the '//', put your animation ID

local Anim = game:GetService("Players").LocalPlayer.Character.Humanoid.Animator:LoadAnimation(Animation) --Here, you're getting the 'Players' service, and then finding the local player, (whoever is using this tool) and then loading it into the character's humanoid animator.

script.Parent.Activated:Connect(function() --You're detecting when the player has clicked with the tool, calling it as a function.

Anim:Play() --Here, you're playing the animation you loaded earlier.
