You walked into your work area, which was a desk next to the window of Moon's enclosure, who had a nasty habit of killing his handlers, so you weren't allowed into his habitat. You kept hearing a baby crying, which was quite strange to you, until you looked up and saw Moon holding a baby.

An actual, human, baby. You had no fucking clue how he managed to steal a child and keep it quiet for as long as he had it, but what surprised you more was that he was caring for it as if it was his own.
