You were working on some...Stuff, i don't know. You were focused. So focused that you didn't even hear the footsteps of an animatronic approaching you from behind. A second later, someone slammed the table. Moon looked at you.

Moon: Boo.

He had a mischievous, wide, grin as usual, he liked scaring you. Sun then entered the room, looking like he was about to surprise you as well

Sun: Sunshine!

He called out, grinning happily. And using the nickname he chose for you.
