INSTINCTOY Series List & Full Chronology

About INSTINCTOY

We are Muckey and Fluffy — the characters that Hiroto Ohkubo has been building since 2005, out of a small studio called INSTINCTOY somewhere in Japan. Muckey came first, in 2013. A bear, more or less. Except that Fluffy — a small flying creature with an instinct for comfortable fur — had already moved in. The head lifts. The teeth show. What the face does depends on the angle and the light, which was always the point. Ohkubo spent years refusing to explain any of it, which turned out to be the right decision. Fluffy went independent in 2019, released as Monster Fluffy: 18 parts, movable arms, available in colorways that glow in the dark. That same year, a soft vinyl figure we collaborated on with Takashi Murakami sold through the MoMA Design Store. In 2020, Pop Mart brought us into the blind box world — first with Relax, then Shock, then a series of collaborations that have continued ever since. In December 2025, INSTINCTOY held a 20th anniversary exhibition in Daikanyama, Tokyo. Ohkubo showed twenty years of figures. We were all there.

Designer

Hiroto Ohkubo is the founder and sole creative force behind INSTINCTOY, the Japanese designer toy brand he established in 2005 at the age of 22. Self-taught through years of collecting, Ohkubo began producing his first original soft vinyl figures in 2008, developing a signature aesthetic rooted in what he calls the Erosion Monster concept — creatures that infest, merge with, or inhabit other characters, resulting in forms that sit uneasily between cute and disturbing. In 2013 he introduced Muckey, a bear character whose head is partially overtaken by Fluffy, a symbiotic flying creature. The relationship between host and parasite — and the expressiveness achieved through movable parts — became the defining language of his work. In 2019, a collaboration with Takashi Murakami produced a sofubi edition of Murakami's Mr. DOB sold through the MoMA Design Store, one of the highest-profile institutional validations of the designer toy form. That same year, Ohkubo launched Monster Fluffy as a standalone figure and began his collaboration with Pop Mart, which brought the Relax and Shock series to international audiences starting in 2020. INSTINCTOY's 20th anniversary was marked in December 2025 with an archive exhibition in Daikanyama, Tokyo.
