Behind the Design: The Mechanics of the "Sushi Roll" Ebi Duck

When the product committee approved The Sushi Roll, a Bushface Duck styled as an ebi (shrimp) nigiri, we faced an existential design crisis. How do you take an iconic duck body, wrap it in a sculpted shrimp tail, replace the face with a lush bush, and still make the base look like sticky rice?

Initial prototypes used a single molded block of white plastic for the rice base. It looked like a duck sitting on a bar of soap. It lacked soul. It lacked texture.

I spent three weeks in our Tokyo design lab testing individual vinyl grain injection. We developed a proprietary micro-molding technique where the lower half of the duck is stamped by a plate containing 4,112 unique microscopic dimples, simulating the irregular surface of seasoned sushi rice.

The hardest part was the face. A standard Bushface has a green boxwood foliage profile. For the Sushi Duck, we modified the leaf chemistry to resemble shredded wasabi leaves. If you look closely at the eyes peeking out from the green, they are tinted with a faint, pale yellow-green ring to emulate the spicy intensity of fresh horseradish. The result is a masterpiece of culinary-industrial design that should under no circumstances be ingested, no matter how hungry you are during a long soak.
