Momo or Mother Bird is a piece of sculpture created by Japanese artist Keisuke Aisawa. The sculpture depicts a human-like figure with bulging eyes, long hair, and bird-like legs and claws. The sculpture gained notoriety when it was shared on social media and falsely associated with a viral internet challenge that supposedly encouraged children to participate in harmful activities. Despite the hoax, the sculpture itself has been described as creepy and unsettling by some viewers.
