Angry Birds was released by Finnish studio Rovio in 2009 and became one of the defining mobile games of its era, built around launching birds at structures. Hal is the green, long-beaked bird introduced as the boomerang bird, whose flight path curves back toward its target. Short clips of character calls like this one later spread through soundboards, YouTube edits and meme videos, where players reuse familiar game noises out of context. The Hal cry survives because it is instantly tied to the series and works as a reaction even without gameplay on screen.
