Ivern was added to League of Legends in 2016 as the Green Father, a peaceful treant who protects the jungle instead of hunting it. His idle animations and voice lines lean into that friendly personality, including long humming stretches that players hear while moving between camps. Clips of the tiritirititi hum were later isolated and shared on soundboards and in stream edits, where the short loop became shorthand for happy wandering. It stays popular because even viewers who do not play League recognize the carefree mood instantly.
