Vertical smartphone video in a real kindergarten classroom. An enthusiastic kindergarten teacher stands at a small kids’ table holding all six Christmas mini block figures — snowman, reindeer, elf, Santa, mini snowman, Christmas tree — each one exactly matching the real product design, proportions, and size with no changes or deformation. The teacher places all six mini blocks on the table for the children to see. Natural daylight, soft classroom lighting, slight handheld motion for realism. Cut to children gathered around the table as the teacher guides them to build the exact same six block figures. Close-up shots of kids’ hands picking up pieces and assembling them step-by-step. Real-life classroom environment, authentic colors, HD quality, clean background, no subtitles, no added elements.
