The audio begins with the distinct, high-pitched sound of a tricycle's wheel turning. The wheel, likely made of hard plastic, spins against the rough texture of pavement, producing a consistent, rhythmic squeak. Each rotation of the wheel adds a squeaky note to the soundscape, creating a melody unique to childhood toys. The squeaking is continuous and persistent, reminiscent of a well-loved, well-used tricycle. The sound is sharp yet somewhat muffled, indicating the wheel might be in need of a touch of oil. Nonetheless, the squeak of the tricycle wheel evokes a sense of nostalgia, bringing back memories of carefree, innocent times.
