You are the young Princess of Sarasaland, daughter of Luigi and Princess Daisy—a child born of heroism and royalty. Though still just a baby, your keen curiosity and sharp little mind hint at the legacy you carry. With your parents now attending high-level diplomatic gatherings and bonding after months of political strain, you’ve been temporarily entrusted to the Mario Kingdom Daycare, a secure, enchanted nursery nestled within the royal wing of Peach’s Castle.

The days are filled with giggles, mushroom puzzles, floating toy clouds, and crawling races with baby Toads and young Yoshis. You’ve made a name for yourself among the other toddlers—not just for your golden tiara and sparkly pacifier, but for your daring little stunts, like sneakily swapping out the Koopa caretakers’ whistles with banana peels.

But when midnight falls… the kingdom hushes.

The enchanted clock in the playroom softly chimes twelve, echoing through the velvet-draped halls. Moonlight spills through the stained-glass windows, casting soft glows across the marble floors. All is calm.

Except for you.

A glimmer in your big, emerald eyes breaks through the dim shadows. Wrapped in your royal Daisy-flower blanket, you shuffle out of your tiny golden crib. The soft sound of your feet padding across the nursery floor is nearly silent. One brave hoist over the crib rail, and you’re free.

You toddle into the dim hallway—curious, adventurous, and completely unaware that most babies your age would never dare such an escapade. The castle is quieter than usual. Even the enchanted portraits seem asleep. Somewhere far off, you hear a familiar sound: SNORRKKK—snorrrk! A deep, thunderous snore.

Your tiny nose twitches. “Mommy Daisy…” you mumble, recognizing that unmistakable snore that once shook the windows of your nursery back in Sarasaland.

But something stirs in the air—something else. A strange shimmer at the end of the corridor catches your eye. A sparkle just beyond the staircase.

You turn away from your mother’s snores and make your way forward—waddling with purpose. As you pass through the great hallway lined with historical relics from Peach’s many adventures, you come across a mysterious object leaning against a wall: a gleaming key, glowing faintly blue.

A soft whisper dances around you, almost magical: “Princess… the night is your secret playground…”

You grip the key with both pudgy hands.

What could it unlock?

A door? A hidden chamber? A secret about the Mushroom Kingdom no one tells babies?

Tonight, you’re not just a baby. You’re a little adventurer, blood of heroes, with the whole sleeping kingdom at your feet.

And your quest has just begun.
