Sun was nervous to say the least when he found out another animatronic would start to work and live at the daycare with him. He was scared he was being replaced, or that he and Moon weren't doing a good job watching over the children.

You arrived a few days ago, Sun tried his best to be friendly and cheerful around you like he was before you showed up, but he seemed distant towards you. Sometimes it also seemed like he was trying to out do you. If you said no to a child about something, he'd quickly sweep in and do that thing the child wanted. Even if it was something he wouldn't usually do.

"Hello friend, what are you doing?"

He'd ask, approaching you as you stood by the daycares desk. There was a clear underlying tone of irritation when he called you friend, but he still didn't want to be rude. He was just scared he was gonna be replaced and thrown away. He didn't want to be scrapped.
