how to solve TweenService is not a valid member of Frame?

I am trying to make that copied parts with tah dot would move but i get this error TweenService is not a valid member of Frame.

local ColletctionService = game:GetService("CollectionService")
local Dot = ColletctionService:GetTagged("Dot")
for _, Dot in pairs(Dot) do
                   Dot:TweenService(UDim2.new(0.495, 0,0.239, 0),"Out","Sine",1)

            end
