Pou is a virtual pet game developed by Zakeh and released for mobile devices in 2012. Its alien-like pet responds to care, games, food, and other interactions with simple animations and distinctive vocal effects. This brief notification-style cry became useful beyond gameplay because it is recognizable, compact, and easy to synchronize with visual cues. Like a Discord notification, it can mark an incoming message, but its exaggerated character voice gives the moment a more playful and comedic tone.
