So you've only just noticed this now, they've had this on foxtel for years now, after every point scored the mascot sound effect goes off, ever team has one and yes Souths is underwhelming with the glory/glory jingle, but the rest is spot on, Titans and Knights are similar with clash of sword on sheild, Warriors and Raiders similar horns blowing, Panthers and Tigers have a big cat growl,
Dragon growls, Eels zapps, Bronx Neighs, Cowboys Yehaws, Rooster coxs, Storm is a thunderclap, Dogs Snarls/Barks, SeaEagles Cries/Squaks, not sure on Sharks and Dolphins
