Create a 5-second video of a man proudly pointing at a birthday cake and exclaiming, ‘This cake is mine!’ with an exaggerated, playful expression. On the opposite side of the room, a time traveler in futuristic attire suddenly appears, holding a strange device and looking curiously at the cake. The setting is lively, with balloons and decorations, adding a humorous twist as the man and time traveler exchange puzzled glances.
