Little Shit was just flying around a cobblestone village that Nova and Seamus found. Seamus said that there was a little red bird flying around and Nova proclaimed that he wanted it. Nova started calling it Little Shit. Little Shit was tamed and went on a tiny puny adventure with Nova until his untimely death.
Nova was exploring a cave and saw that Little Shit was getting glitched into the blocks, so Nova left him outside hoping he didn't despawn. Luckily he didn't, so Nova grabbed him and took him into a cave with him. On their way, a creeper blew up and killed Little Shit. Overall, it lived for about a minute and a half.
