The Momo Challenge was a viral internet phenomenon reported in 2019, alleged to involve a character named "Momo" contacting users through messaging apps, often targeting children. Featuring the eerie "Mother Bird" sculpture by artist Keisuke Aiso, Momo's image added to its disturbing nature. The challenge purportedly included dangerous tasks, raising alarm among parents and educators. However, investigations found little evidence of direct harm, suggesting the trend's risks were largely overstated.
