Pou is a virtual pet game for mobile phones in which players feed, clean and play with a small alien creature, and its quirky vocal sounds became part of the game's charm. Fans began lifting short clips, including this notification-style squeak, for ringtones, alerts and soundboard pages, especially in Spanish-speaking communities where it is shared as a Pou notificación. Its appeal has lasted because the sound is instantly recognisable, easy to drop into a joke and short enough to reuse without wearing out its welcome.
