"Time for bed, Luna," Xenophilius said as he stood in the doorway of Luna's room, where the four-year-old was rolling Gobstones for Newt to chase.

"But I'm not sleepy, Daddy!" she protested. "Can't I stay up a bit longer?"

"No, moonbeam, you need your sleep. Come on, into bed with you."

"No!" Luna said stubbornly with her lower lip sticking out and her arms crossed over her chest.

"If you get into bed now," Xeno told her, "Daddy will read you a bedtime story." At this, the little girl quickly climbed into her bed and sat up, eagerly awaiting story time.

"Read about Babbity Rabbity, please?" asked Luna. Xeno nodded and read that to her; the little girl was sound asleep by the time he had finished.

Pandora woke up in the middle of the night to strange sounds coming from downstairs. "Xeno, wake up," she whispered, shaking her husband.

"Huh? Wha' is it, Dora?" he mumbled groggily.

"There's something moving downstairs. Come on!" Xeno suddenly sat bolt upright as the sounds reached his ears.

"It could be an Umgubular Slashkilter!" he said in alarm.

"Perhaps...or it could be a burglar," his wife replied. "Either way we need to investigate; now, come on!" They quickly headed downstairs.

To their surprise, they found none other than Luna walking around in the kitchen, her eyes closed. "Sweetheart, what are you doing up?" Pandora asked. "It's past your bedtime."

But Luna did not respond; she didn't even seem to hear her mother. Instead, she seized a fork and began swiping the air with it while mumbling "Take that, you Nargle!"

A look of realization came over Xeno's face. "Dora," he said quietly. "I think our daughter is sleepwalking."

"Are you sure?"

"Yes." He gently tapped Luna on the shoulder. "Luna, can you hear me? Luna?"

The little girl's eyes fluttered open and she gave her head a little shake. "Daddy?" she whispered. "Why am I in the kitchen? And why am I holding a fork?"

"I'll explain later," Xeno said softly, leading Luna back upstairs with Pandora following close behind. "Let's just get you back into bed."

Once Pandora and Xenophilus were back in their own bedroom, Pandora asked, "How did you know Luna was sleepwalking?"

"Because sleepwalking runs in my family," answered Xeno. "My father was a sleepwalker, as was one of my aunts."

"Well, that makes sense. In any case, I think I can brew a potion tomorrow that will help Luna. It won't completely cure the sleepwalking, but it can help reduce the number of episodes. But first I need to explain to her what happened."

"Dora, I told her I would explain."

"Don't worry about it, Xeno. I can do it." She sighed inwardly. Explaining sleepwalking to a four-year-old was not going to be easy.

"Sleepwalking?" Luna asked the next day. "What's sleepwalking?"

"Basically what the name says," her mother told her. "You were walking in your sleep."

"But why?"

"I don't really know, sweetie. This is just something some people do, something they can't control by themselves. But I'm going to make a potion that will help you sleepwalk less."

"Is it going to hurt?"

"No, I don't think so."

"Will it taste bad?"

"Well, sweetie, there is an old saying that anything that tastes bad has to be good for you," Pandora said. Luna made a face at this.

"Like carrots?" she asked.

"Well, yes."

"Then I'm not taking the potion," said Luna, crossing her arms.

"Luna, would you rather take a potion that tastes bad or sleepwalk every night for the rest of your life and possibly get hurt or even hurt someone else?"

The four-year-old pondered this for a minute and then said, "Oh, okay, Mummy. I'll take it."

The potion was ready by the following evening. About an hour before Luna's bedtime, Pandora carefully carried a small cup of it to Luna's room, where the little girl was drawing a picture of Moon Frogs of many different colors hopping across the moon. "Time for your potion, sweetheart," she said, handing the cup to Luna, who took a small sip before making a disgusted face and spitting it out.

"Yucky!" she cried.

Pandora sighed. "I know, sweetie," she said. "You only need to take a little more." Luna slowly sipped the rest of the potion and, pulling a face at the taste, swallowed it.

"Good girl," Pandora said. "Now, you'll need to take this potion every night around an hour before you go to bed."

"Every night?!" Luna repeated, horror-struck.

"Every night. You'll get used to it."

When Pandora came to tuck Luna into bed later that night, she noticed the little girl had put her shoes back on. "Luna, why are you wearing your shoes?" she asked.

"Just in case I sleepwalk again tonight," Luna answered. "I probably won't, but you never know."

"Good thinking, sweetheart. Now what story would you like to hear tonight?"

"The Three Brothers!"

As Pandora lay in bed hours later, she thought about her daughter's sleepwalking problem and how this was something the family would have to adjust to...unless she discovered an actual cure, which she sincerely hoped she would one day.
