yeah, Lego Robotic Contest ,sounds the same one i've mentioned,
we got the courses in Children's Palace too.
during that time.BB was happy with the Robot while i enjoyed shopping around,making a health spa and facial care.
i once joked with my kid that we not only spent much money on Lego,but on mom's face,was that worth it?later when he got the reward,he answered proudly that it was indeed worth.
