Art style: Pixar-like 3D.
A premium 3D cartoon classroom at eye-level. In the centre, a large digital whiteboard displays a vibrant, colourful mystery box wrapped in a bright yellow ribbon. The box is surrounded by magical golden sparkles. Miss Irina stands in the centre in her teal blouse, Ksenia is on the left in her pink sweater, and Maxim is on the right in his navy sweater. All characters look at the box with expressions of wonder.
