Terence debuted as the largest bird in Rovio's Angry Birds flock and returned in Angry Birds 2, the 2015 sequel to the hit mobile game. Unlike the other birds he rarely makes cute chirps, communicating instead through deep growls that contrast with his still expression. That joke carried into the animated films and later clips shared online, where fans isolated his grunts as reaction sounds. The clip stays popular because one low rumble instantly identifies the character and works for anger, size and deadpan intimidation gags.
