Summary: 3rd in my little series of Oneshots about Pitch and MiM being brothers (I'm thinking of calling the series moonbeams and butterflies but I don't know). Anyway moving on; During a visit to Earth, Manny hears a lullaby he used to sing to his little brother.

The man in the moon sighed as he walked alone down the street. Every few years he liked to come down to Earth and poke around, see what was happening and how everything was going on.

He smirked as he saw Jack Frost fly by out of the corner of his eye. He loved watching Jack have fun and had had quite a few encounters with the boy on his visits to Earth. It was especially fun since Jack had no idea that he was doing it!

One of the perks of being skilled in magic and immortal, you could alter your appearance. For the last few hundred years though, Manny had stuck to how he looked when he was 24. Black-hair, Blue eyes, pale skin and the build of a football-star.

Manny smiled to himself when he saw the horde of children following the winter spirit. "He has a little fan-club!" MiM chuckled.

Just then out of the corner of his eye, Manny saw something shiny sitting abandoned on a bench in the park where Jack had just flown by. Racing over to see what it was, MiM was surprise to see it was an ipod.

"One of the kids must have forgotten it when Frost flew by." He thought to himself as he looked the device over. He'd never seen an Ipod up close before and was curious to see what it did.

The Man in The Moon started to press buttons on the electronic which made it start playing a song that was all too familiar to Manny.

"SILLLLLLY!" A loud scream called out to the sleeping 12-year-old Silice. With a sigh, the young boy forced him out of his bed and lazilly walked down the hall to his little brother's room.

His 7-year-old brother Kozmotis was hiding under his quilt and pillow, only his eyes visible as the older of the two came in and sat down on the edge of the bed. "Kozmotis? What's wrong?"

"There's a monster under my bed!" His brother squeeked out, disappearing completely under his blanket and making his older brother roll his eyes.

"Kozzy, you sleep on a futon. How can a monster fit under it?" He asked.

"Why don't you ask him!" Kozmotis hissed, not coming out from his hiding place.

Silice groaned and got down on the floor, looking under the futon for a quick second and then looking back up at his brother. "Nothing."

Kozmotis still didn't come out from under his covers,"You sure?" He squeeked.

"Positive." Silice smiled softly, "No monsters here."

After thinking everything over for a minute, Kozmotis's pulled the quilt down to his waist, smiling a little bit. "Thanks Silly." He said softly.

"No problem Kozzy, goodnight." Silice was about to get up when his brother grabbed his arm.

"No! Silly! No!" He protested and Silice stared at him in confusion.

"What now Koz?"

Kozmotis was silent for a few minutes before saying so softly that Silice could barely hear him. "Can you sing me a lullaby, like mama used to?"

Silice smiled sadly, melting a bit. He couldn't say no to his baby brother, he was just too cute! "Alright Kozzy, but go right to sleep okay?"

The 7-year-old smiled happily, snuggling down in his bed as his brother began to sing a song. A song that hopefully, would put his brother's nightmares to rest.

Silice: There's a monster that lives 'neath your bed

Oh for crying out loud it's a futon on the floor

He must be flat as a board

There's a creature that lurks behind the door

Though I've checked there 15 times

When I leave then he arrives

Every night

Tell the monster that lives 'neath your bed

To go somewhere else instead

Or you'll kick him in the head

Tell the creature that lurks behind the door

If he knows what's good he won't come here no more

Cause you'll kick in his butt at the count of four

Goodnight demon slayer, goodnight

Now it's time to close your tired eyes

There are devils to slay and dragons to ride

If they see you coming, hell they better hide

Goodnight, goodnight, goodnight

Goodnight my little slayer goodnight

Tell the monster that eats children, that you taste bad

And you're sure you'd be the worst he's ever had

If he eats you, don't you fret, just cut him open with an axe

Don't regret it, he deserved it, he's a cad

Tell the harpies that land on your bed post

That at the count of five you'll roast them alive

Tell the devil it's time you gave him his due

He should go back to hell, he should shake in his shoes

Cause the mightiest, scariest, creature is you

Goodnight demon slayer, goodnight

Now it's time to close your tired eyes

There's devils to slay and dragons to ride

If they see you coming, hell they better hide

Goodnight, goodnight, goodnight

Goodnight my little slayer goodnight

I won't tell you, there's nothing 'neath your bed

I won't sell you, that it's all in your head

This world of ours is not as it seems

The monsters are real but they're not in your dreams

Learn what you can from the beasts you defeat, you'll need it for some of the people you meet

Goodnight demon slayer, goodnight

Now its time to close your tired eyes

There are devils to slay and dragons to ride

If they see you coming, hell they better hide

Goodnight, goodnight, goodnight

Goodnight my little slayer goodnight

Goodnight, goodnight, goodnight

Goodnight

As Silice finished his song, he smiled down at Kozmotis who had fallen asleep to the soothing sound of his older brother's voice. He was smiling in his sleep, dreaming of himself as a brave and powerful warrior, respected by all and making all the monsters in his world shake and quiver when they saw him coming.

The older boy chuckled and kissed his brother's forehead, "Goodnight my little slayer."
