The process involves a rapid metamorphic calcification combined with bio-polymer synthesis: Beanoids have specialized cells in their arms that produce a super-dense bio-mineral composite (a mix of calcified structures and alien bio-polymers). These cells are activated by a neural or hormonal signal triggered when the beanoid decides to form a blade. The skin and tissue undergo rapid ossification (calcification) along predetermined pathways, similar to bone growth, but much faster. 2. Blue Coloration: The blue color could come from trace metals (like cobalt or copper) stored in the blood or specialized organelles. These metals integrate into the calcified structure during blade formation, giving it extra strength and a striking appearance. 3. Sharpness and Toughness: The bio-mineral composite forms an ultra-hard ceramic-like edge. The surface is coated with a keratin-like substance, polished during the transformation process to maximize sharpness. 4. Shapeshifting Mechanism: The arm blade is semi-retractable, with specialized collagen-like tendons and muscles that allow the blade to revert into its softer, flexible state when not in use. A complex enzyme-driven process breaks down the calcified structures quickly, allowing the arm to regain normal function. 5. Energy Source: This transformation likely consumes immense amounts of energy, so beanoids might have: Energy storage organelles (like fat reserves or glycogen stores) dedicated to this process. A highly efficient metabolism capable of rapidly generating the required resources. 6. Alien Evolutionary Context: This adaptation might have evolved for survival in a hostile environment where beanoids needed to hunt or defend themselves. The calcification mechanism could have been an evolved form of protective armor that became weaponized over time.
