The kit is set for release on Saturday, September 5, 2026, at a price of 1,925 yen including tax. The Steller's sea cow model follows the series' two-build system: a skeleton build that lets assemblers learn the internal structure, and a dinosaur build where integument parts are attached over the skeleton. The skin parts include fine wrinkles molded into the surface, reproducing the animal's physique, which stored fat for adaptation to cold regions. Articulation covers the mouth, head, neck, arms, abdomen, and tail flukes, allowing the model to be posed in a swimming stance on a clear base included with the kit. Assembly is snap-fit with no adhesive or tools required, and parts pop off runners with a touch-gate system. The kit is non-scale and includes a sticker sheet and the base.","whyItMatters":"The Steller's sea cow kit continues the Gachikoseibutsu Club series' pattern of applying its skeletal and skin assembly system to animals beyond dinosaurs, in this case a marine mammal known for its extinction in 1768.","webCardHtml":"\u003cp\u003eThe Steller\u0026#39;s sea cow kit arrives on the same day as the Archelon, another new member of the Gachikoseibutsu Club line. Archelon is the largest turtle in history, with a lightweight special shell that kept its massive body from being crushed. That kit carries a 1,760 yen price, below the sea cow\u0026#39;s 1,925 yen.\u003c/p\u003e\u003cp\u003eThe Gachikoseibutsu Club name marks kits tied to an anime, while the main PlanoSaurus line stays focused on dinosaurs. Both new releases use the touch-gate system, where parts pop off runners by hand, and snap-fit assembly that needs no adhesive or tools.\u003c/p\u003e\u003cp\u003eArchelon lived in the Late Cretaceous period. Its mouth opens and closes, and its neck, limbs, and tail move, so it can be posed swimming.
