A steam locomotive made entirely of prickly pear cactus, chugging through a vast desert landscape on tracks of intertwined roots and vines. The train’s body is covered in thick, green cactus pads, with bright flowers blooming along the roof. The chimney puffs out soft clouds of golden pollen, shimmering in the sunlight. Passengers in the form of tiny cactus creatures peer out from spiky, round windows, waving excitedly. The train’s wheels are made of smooth, polished stone, with green vines wrapping around them like natural gears. Along the tracks, desert foxes and tumbleweeds roll by, while the sun sets behind distant cactus mountains, bathing the scene in warm orange and pink hues.
