Art style: 3D Pixar.
请生成一张竖屏 9:16 的温暖日系 2D 动画插画。场景是同一个晚上、同一个小公寓客厅。阿杰蹲在茶几旁或坐在地毯上，正在打开一个大快递箱。箱子里露出一个非常巨大、奇怪又可爱的枕头，形状像一朵云或一只很圆的奇怪动物，颜色柔和但体积夸张，几乎占了半个茶几和沙发空间。阿杰穿红黑格子睡衣，表情兴奋又自豪。小雨穿黑色宽松卫衣和白色居家长裤，站在或坐在旁边，拿着杯子，表情惊讶又不太相信，像在想“这到底是什么”。客厅温暖、柔和、生活感强。不要字幕，不要文字，不要水印。

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image in the following art style:
Pixar-style 3D computer animation (Pixar / Disney feature-film look) — fully volumetric 3D rendering with rounded dimensional forms, soft subsurface-scattering skin, physically based materials, soft global illumination, warm cinematic key light, gentle depth of field, vibrant family-friendly colours. CRITICAL: EVERY element — characters, foliage, trees, animals, water, sky, props and the entire environment — must be rendered as polished 3D CGI with real depth and form. This is NOT flat 2D illustration, NOT a watercolour or storybook painting, NOT cel-shaded anime.
Every surface, skin, fabric, material, and environmental element must be rendered in this idiom.
