Resultado da Watching Tubbo’s stream a couple of days ago I realized we might be getting one. He was acting very strange, he kept snapping at Sunny for random things like pointing at him or making loud sounds, and seemed to be angered at Richard and was angered by the way his field was slightly damaged.
