Another day, another Nintendo Dream! This time on Malfestio!


 * After Great Maccao was finished early in development, the team wanted to make another unusual monster that could use status effects. They wanted this strange monster to have a novelty to it that past monsters lacked, so they made it a Bird Wyvern based on owls. The development team also wanted it to be able to turn around completely before quickly performing an attack.
 * In early concepts, Malfestio was similar to Great Maccao in many ways. In those concepts, it used its rear legs and "forearms" to fight.
 * Malfestio's sleep beam is described to be an ultrasonic humidifier by the director and producer. Malfestio has a special narcotic liquid in its sleep sac. It fires this liquid at enemies by using its ultrasonic vibrations to atomize the liquid and spray it at prey.
 * Around Malfestio's wing webbing, the scales gather sound and emit a strange echo pattern. These are ultrasonic vibrations it produces from its wings.
