Animal Jam is a children's online virtual world launched by WildWorks in 2010, where players explore as animal avatars and can send each other in-game mail. The mail chime plays whenever new mail arrives in the player's den, and longtime players know it instantly. As the game's fanbase grew up, clips of its interface sounds began circulating on YouTube compilations and soundboard sites, where it sits beside game notification sounds like the GTA V notification. Today the chime shows up in nostalgic gaming edits and as a generic 'message received' ping for creators who never played Animal Jam.
