  1. 1

    At the park’s oldest chestnut tree, Bao noticed a golden bead of sap shining like a tiny sunrise. Sao sniffed the bark, and his star pendant gave one bright wink. Then a round door, no bigger than Bao’s backpack, clicked open under a curl of moss.

  2. 2

    Inside, the tree was not dark at all. Amber sap lamps glowed along smooth tunnels, and a little acorn train waited on silver roots with a chimney puffing cinnamon steam. “It’s a railway,” Bao whispered, and Sao’s tail wagged hard enough to stir the dust.

  3. 3

    A squirrel in a knitted cap rolled up beside them on a walnut cart, balancing bowls of berry porridge. “Morning delivery!” she chirped. “The tree mice are waiting at Root-End Nook, but my helper has the hiccups.” Bao stood taller. “We can help.”

  4. 4

    The squirrel gave Bao a curled bark map, ridged with lines he could feel under his finger. Sao leaned close, nose twitching over the winding paths. One route dipped past Mushroom Station, one looped by the sap mill, and one thin track led toward breakfast.

  5. 5

    Bao tucked the bark map safely into his backpack pocket, where its corners peeked out like little wings. Sao hopped into the front acorn car, paws on the rim, eyes shining. With a happy clack, the train rolled forward, promising breakfast, tunnels, and one very careful choice.

  6. 6

    At Mushroom Station, a squirrel conductor unrolled a soft bark map that curled like a sleeping leaf. Golden sap lines shone and faded, showing tunnels named by smells: honey-warm, rain-cool, crumbly-nut. Bao leaned close while Sao’s pendant twinkled against the map’s glow.

  7. 7

    The breakfast baskets smelled of oat cakes, berry caps, and thistle tea wrapped in warm moss. Bao helped tuck them into the tiny acorn carriage, proud to be careful. Sao hopped onto the front bench and whispered, “Tree mice breakfast, here we come.”

  8. 8

    The train clicked into the honey-warm tunnel, where sap lanterns bobbed like little suns. Ahead, two silver rails split around a knobbly root. Bao checked the bark map, but Sao spotted a painted chestnut shell and chirped, “That way looks shorter!”

  9. 9

    Wanting to help, Bao pulled the smooth little switch before he matched the root shape on the map. The rails clacked, the acorn train tipped gently to the left, and Sao’s ears popped up. The honey-warm smell changed to peppery pine.

  • 10

    The train rolled out beside a busy squirrel workshop, where wooden wheels spun and nut shells chimed in neat bowls. A little squirrel blinked at the breakfast baskets and said, kindly, “Oh dear—tree mice live three tunnels over.” Bao’s cheeks warmed as the train ticked softly behind him.

  • 11

    The acorn train burst from the sap tunnel into a round hollow where three tracks curled away like chestnut ribbons. Bao saw their breakfast cart rattling toward a sign carved with sleeping bat shapes, not the cozy mouse burrow from the bark map. Sao’s ears dipped. “That switch,” he whispered, “wasn’t the morning track.”

  • 12

    The squirrel conductor skidded up with a lantern made from a dewdrop. Bao hugged the bark map to his chest, cheeks hot, because he had nodded when Sao tugged the lever. Sao stepped forward anyway. “I pulled it wrong,” he said softly. “Bao trusted me, and the mice are waiting.”

  • 13

    No one scolded. The conductor only tapped the map where a line of pale sap dots crossed a tiny knot-hole. Bao breathed out and noticed the same pale dots glowing above the left-hand rail. “The bark map isn’t just lines,” he said. “It matches what the tree is showing us.”

  • 14

    Bao climbed to the little switch bridge while Sao ran below, matching the glowing dots with his nose. “Ready?” Bao called. Sao flicked his tail once for yes. Together they eased the lever back, and the rails clicked with a gentle wooden clack, not a crash.

  • 15

    Far down the tunnel, the breakfast cart slowed, shivered, and rolled onto the mouse-burrow track. A warm smell of toasted seeds drifted back, and Bao’s shoulders loosened. Sao pressed his star pendant between his paws. “I still feel wobbly,” he said. Bao smiled. “Me too. But we’re helping it right.”

  • 16

    At the fork, the bark map curled like a sleepy leaf, and Bao saw the tiny notch he had missed. His cheeks warmed. “I moved the breakfast switch wrong,” he told the squirrel conductor. “I’m sorry. Can I help make it right?”

  • 17

    No one scolded. The conductor handed Bao a smooth seed-lantern, and Sao pressed his nose to the bark grooves. Together they traced the raised river-line, the mushroom mark, and the little mouse-door shape until the safer breakfast route gleamed ahead.

  • 18

    Bao tugged the switch back with both hands, and Sao gave the signal bell one bright tap with his paw. Click-click, the acorn train rolled from the wrong tunnel into the golden one. The porridge pots stopped wobbling, and the berry baskets settled with soft plunks.

  • 19

    The train puffed into a station tucked behind a curtain of moss, where tree mice waited in acorn-cap slippers. Bao carried the first basket down himself. “I made us late,” he said, “but we brought it warm.” The smallest mouse smiled with berry-purple whiskers.

  • 20

    After breakfast, the mice gave Bao and Sao two chestnut crumbs wrapped in a leaf for the ride home. Bao tucked the bark map carefully into his backpack, not to hide the mistake, but to remember how they fixed it. Sao leaned against him, warm as a little sunset.
