B'Mo the adventure dog trotted eagerly through the wide entrance, his nose twitching as he sniffed the cool, recycled air. The mall felt endless, every footstep reverberating off polished tiles and glass. Somewhere between the silent food court and the shuttered toy store, an odd, metallic humming caught B'Mo's keen ears.

The Walbus loomed—an enormous, retrofitted city bus emblazoned with the faded logo of a long-forgotten supermarket, its headlights casting eerie circles on the tiled floor. Its doors were wide open, and the inside glowed with an inviting, otherworldly blue. B'Mo pawed at the ground, tail wagging, curiosity drawing him closer.

B'Mo stepped cautiously onto the rubber floor, his claws clicking as he explored. "Hello? Anyone here?" he barked, voice echoing strangely. The bus seemed to stretch and shift behind him, as though the space inside was larger than the outside.

Wind rushed past as B'Mo pressed his nose to the glass, watching mannequins wave from a passing shoe store and fountains splash with shimmering, colored light. "This isn't just a bus... it's a portal!" he exclaimed, heart pounding with excitement and a hint of fear.

Stepping off the Walbus, B'Mo was greeted by a chorus of robotic voices and the clatter of unseen tokens. Somewhere in the shadows, a friendly, spectral mall attendant waved, beckoning him deeper into the arcade's maze. "Welcome, traveler! The adventure's just begun," the attendant called, voice echoing through the neon haze.

B'Mo bounded forward, his adventurous spirit undampened by the strangeness around him. Each corner promised new mysteries, each echo whispered with the promise of discovery. "There's magic in these liminal spaces," he thought, tail wagging as he disappeared into the ever-changing heart of the mall.
