How to tween children of a part?

I am trying to make a part and its children to expand in size when the remote event is fired. When I tweened the parent it wouldnt tween the children so I tried to use a looped search to get the children of the part but it only tweens 1 part. Do I need to individually tween each part?

Code:

local remote = game.ReplicatedStorage.HeavyPunch
local DB = false

remote.OnServerEvent:Connect(function(Plr)
	
	local PlrDB = {}
	
	local Char = Plr.Character
	local Hum = Char:WaitForChild("Humanoid")
	local HumRoot = Char.HumanoidRootPart
	
	local partloc = game.ServerStorage.Classes.UnArmed.HeavyPart
	local Punch = partloc:Clone()
	
	Punch.Parent = workspace
	
	Punch.CFrame = HumRoot.CFrame + HumRoot.CFrame.LookVector*1
	Punch.HeavySound:Play()
	
	for i, v in pairs(Punch:GetChildren()) do
		
		local TS = game:GetService("TweenService")
		local Info = TweenInfo.new(
			0.5,
			Enum.EasingStyle.Quad,
			Enum.EasingDirection.Out,
			0,
			false,
			0
		)
		
		local Goals = {
			Size = Punch.Size*5
		}
		
	local TweenMain = TS:Create(Punch, Info, Goals)
	
	TweenMain:Play()
		
		end
	
end)

On line 36, replace Punch with v because v are all the different children of Punch which is what your trying to tween.

local TweenMain = TS:Create(v, Info, Goals)
