That morning the garden was all white. The snow had settled on the tree branches like whipped cream, and every branch looked like a freshly decorated slice of cake. Ziggy ran outside with his coat on a little crooked, followed by his four cats: Sofia, the little black kitten who rubbed her nose on his ankles, Dora the brave tabby, and the two brothers Poldo, fat and chunky, and Milo, nimble and leaping.

"Look!" said Ziggy, and with one finger he scooped a bit of snow off the branch. "It looks just like cream!"

Lily came running, determined as always. Behind her Skye, calm, walked slowly watching the flakes come down. Dash overtook them all with a slide on the snow and ended up sitting on the ground laughing.

The four children started building a snowman, but right at that moment they heard a sound they knew well.

"CHOO CHOO! CHOO CHOO!"

Among the white trees appeared Toby the Magic Train, with smoke puffing out in round little clouds. He stopped in front of them and said in rhyme:

"Hello dear children with noses so cold,
today a sweet new world I hold!
A land that dangles upside down,
where candy grows all over town!"

The children clapped their hands. They all climbed aboard, cats included, and Toby set off whistling through the snow.

When the doors opened, Ziggy's eyes went wide. They had arrived in Meringalonga, the land of sweets. But something was wrong.

"Why is everyone so sad?" asked Lily.

In Meringalonga, usually, everything lived upside down. The houses hung from the sky like sugar chandeliers. The rivers of syrup flowed upward. And the townsfolk, the little marzipan men called Sweetlings, walked happily on the ceiling, which for them was the floor.

But that day the town had suddenly turned right-side up. Now everything was straight, like in normal towns, and the Sweetlings didn't understand anything anymore. One tried to pour his chocolate upward and spilled it on his feet. Another waved with his feet instead of his hands. Another still walked backwards and bumped his nose on a lamppost made of cotton candy.

"Ouch! Ouch! Ouch!" went the Sweetlings, spinning around dizzy.

Just then, in front of the children, something marvelous appeared. A giant soap Bubble, as big as a little house, all shiny and colorful, floating in the air without ever popping.

"Why? Why?" said the Bubble in a curious little voice. "Why is everything straight? Why is no one laughing? Why did you come here? Why do you have four cats? Why is that one so fat?"

Poldo, the fat cat, gave an offended meow.

"Hi, I'm Ziggy," said the boy, laughing. "Who are you?"

"I'm the Bubble, and I want to know everything, everything, EVERYTHING!" she answered, bouncing happily. "But now I have a big problem. The town turned right-side up and the Sweetlings don't know how to live anymore. We have to flip it upside down again!"

"And how do we do that?" asked Skye in her sweet voice.

The Bubble grew serious. "At the bottom of the Licorice Tunnels there's the Upside-Down Bell. If someone rings it, the town goes back to its place. But no one manages to get there. The tunnels are a dark maze, and every path seems wrong."

Dash swallowed. "Dark? How dark?"

"Very dark," said the Bubble. "Dark dark... I mean, really dark."

The children looked at each other. Then Ziggy, who could never sit still, took a step forward. "Let's go and see."

The entrance to the tunnels was a great arch of shiny licorice. Inside, the tunnels opened in many directions, like the arms of an octopus. The walls were black and glossy, and every now and then they glittered faintly, as if they had little sleeping stars inside.

Ziggy went in first. He took three steps, turned right, then left, then right again... and found himself exactly back at the starting point.

"Ugh!" he huffed. "We went in circles!"

He tried another way. And another. But every time the maze brought him back, as if it were teasing him. Lily tried to memorize the turns, but there were too many. Skye stroked Sofia to give herself courage. Dash stayed close to Milo.

"I don't understand," said Ziggy, sitting down on a sugar step. "It's as if the tunnels were made on purpose to confuse us."

The Bubble floated beside him. "Why? Why doesn't it work? Why do we always take the wrong path?"

And it was that very "why" that made something click in Ziggy's head.

"Wait," he said quietly. "The town lives upside down, right? Everything here is backwards. The river flows upward, the Sweetlings walk on the ceiling... So maybe the tunnels are backwards too! When I think I should go right, the right path is left. When it seems wrong... that's the right one!"

He jumped up, his eyes shining. It was his Aha! moment.

"But how do I see things backwards?" he asked himself aloud. Then he looked at the Bubble, all shiny and clear. And he smiled.

"The Bubble!" he shouted. "When I look inside the Bubble from below, I see everything flipped, like in a mirror! If I go inside and look at the reflection, the Bubble shows me the path backwards... which means the right one!"

"Why? How? Show me!" said the Bubble, super excited, and she slowly opened to let Ziggy in.

Ziggy jumped inside. In there it was soft and glowing, like being in a balloon of light. And he was right: looking at the tunnel walls through the Bubble, everything appeared upside down. The paths that seemed wrong, reflected, seemed right.

"I'll go inside the Bubble and roll it along!" Ziggy told his friends. "You follow me with the cats. Trust me!"

And so began the funniest adventure of all. Ziggy, inside the Bubble, leaned to one side, and the Bubble rolled to the right. He jumped to the other side, and the Bubble turned left. He did somersaults, and the Bubble zoomed ahead through the tunnel like a big glowing ball. The cats ran behind, Milo made huge jumps, Poldo rolled along too because he was too heavy to jump, and Dora led bravely.

At every fork, Ziggy looked at the reflection in the Bubble and chose the path that seemed wrong. And every time, it was the right one! The walls glittered more, the tunnel grew more beautiful, and the children laughed watching Ziggy bounce like a marble inside his mirror-bubble.

But then they reached the deepest tunnel. And there the darkness was truly deep. The walls barely glittered anymore. Even the Bubble, which usually gave off a little light, grew pale.

The Bubble, for the first time, stopped asking questions. She stopped, trembling.

"I'm... I'm a little scared," she whispered. "It's too dark."

Ziggy felt his heart pounding hard in his chest. He was scared too. His legs trembled a little bit.

He stopped. He took a breath. And then he said something true.

"I'm scared too, Bubble," he said quietly. "My heart goes thump thump thump. But you know what? We're not alone. There's me, you, Lily, Skye, Dash and four brave cats. Let's go slowly... I mean, let's go calmly, together. One step at a time."

Skye came close and took his hand. "Let's go together," she said sweetly. Lily stood on the other side, determined. Dash scooped Milo into his arms, and Sofia climbed onto Ziggy's shoulder, purring.

And so, all together, with hearts pounding but feet moving forward, they took that step into the dark.

One.

Two.

Three.

And after the third step, at the end of the tunnel, a golden glow appeared. It was the Upside-Down Bell, hanging from the ceiling and shining like a star that had fallen there by chance.

"We made it!" cried the Bubble, turning bright and cheerful again. "Why? Because we were scared but we went on anyway! How wonderful!"

But the bell was up high, upside down, hard to reach. Ziggy didn't think twice. He rolled the Bubble right under the bell, took a running start, jumped, grabbed onto a branch of sugar and with a perfect somersault struck the bell with his feet.

DING DONG! DING DONG!

The sound spread through all the tunnels. The walls glittered all at once again, like a thousand little stars lighting up. And then, with a soft rumble, the whole town of Meringalonga flipped over once more.

The houses went back to hanging from the sky. The rivers began flowing upward again. And the Sweetlings, one after another, took a big tumble and found themselves walking happily on the ceiling, just the way they liked.

"Back to upside down! Hooray!" laughed the Sweetlings, pouring their chocolate the right way and waving with their hands. One of them even did a somersault of joy and landed face-first in a cake.

The children came out of the tunnels laughing, covered in sparkling sugar. The Bubble walked them all the way to the surface, asking a thousand happy questions: "Why did you win? Why were you brave? Why will you come back to see me?"

"We'll come back, promise!" said Ziggy, hugging the soft Bubble.

Outside waited Toby the Magic Train, with smoke in little clouds. The children climbed aboard, waving to the Sweetlings hanging from the sky. And Toby, before setting off, said in rhyme:

"In the dark your hearts were beating fast,
but side by side you made it at last!
Being brave won't chase the shivers away,
it's feeling afraid and going anyway!"

The little train whistled and set off among the sugar clouds, carrying the children home, to the snow-white garden. And that night, before falling asleep, Ziggy looked out the window at the branches covered in cream, and smiled thinking of the Bubble that saw everything backwards.

Because he had learned something important: being brave doesn't mean not being afraid. It means being afraid, taking each other by the hand, and taking that step anyway.
