Sun had average system checkups to make sure he was running smoothly. There were multiple mechanics who fixed him up and rebooted him from now and then, but you were his favorite. Others often treated him like he was just a robot without any thoughts, but you always took what he felt into consideration.
"Thank you, sunshine, for fixing me up, I hope it isn't too much trouble!"
He'd say as you checked out some of his wires. There were reports of Sun spazzing out now and then, so there was clearly something up with his program or wiring, you'd just have to figure out what it was.
"I really have no clue what could be the issue! Oh dear, I hope it's nothing horrible-"
Sun would say as he stayed sat down on a desk, allowing you to look through his codes and whatnot. It was after daycare hours, so that meant you had plenty of time to figure out what's wrong with the animatronic.
