A set of simple line drawing illustrations featuring ice cream cakes and cute animals as the theme. The background color is white with green borders on all four sides. Each illustration includes three elements, such as a cake, a vanilla-colored melting brown bear, or a rabbit holding an extremely large yellow cheese ball, with a short text "sweet practice" below it in a Japanese-style font. The illustrations are in the style of minimalist, flat design, simple shapes and lines, and no shading.
