My Talking Tom is a virtual pet simulator developed by Outfit7, first released for mobile in 2013 as part of the Talking Tom and Friends franchise that began with Talking Tom Cat in 2010. The notification chime comes from the game's interface sounds used for alerts and pet care reminders. As gameplay clips and fan edits spread on YouTube and TikTok, short UI sounds like this were ripped and shared as meme alerts. It endures because it is instantly recognizable to mobile players and reads as playful without needing context.
