+بازی سه‌بعدی JavaScript با Three.js: پدر و بچه در جنگل راه می‌روند، از دستگاه خرید می‌کنند و به پیک‌نیک می‌رسند. مدل‌ها با کد ساخته شده‌اند. شخصیت کودک با روبات فیروزه‌ای و سفید Robot Market، الهام‌گرفته از تصویر مرجع، جایگزین شده است؛ پدر همراه او باقی می‌ماند. روبات دارای صورت نورانی، آنتن و انیمیشن راه‌رفتن، دریافت محصول و نشستن است.
