Baby gender reveal ideas/game

Looking for a skilled freelancer to help me create a fun and interactive baby gender reveal game for a physical gathering. I have in mind something like a Mario Bros stage, and at the end, when the flag goes down, change the color of the baby (blue/pink) or a race track like mario kart, and at the end shows a trophy in baby color (blue/pink) or any other ideas are welcome

Im looking for something cheap, but creative, let me know what you have already done and ready to use, good luck thanks!!!
