Every night after the family falls asleep or goes out, a secret world comes alive inside the house. Tom, a plush teddy bear who adores Tomica miniature cars, climbs into a tiny vehicle and sets off to explore every corner of the home. Joined by a cast of fellow stuffed animals—a nervous mouse who often causes accidents, a trendy rabbit with a love for fashion, a competitive moon bear who sees Tom as a rival, and a calm Tibetan sand fox who maintains the hidden Tomica garage—Tom turns ordinary rooms into vast adventure grounds.

The setting is the everyday interior of a family home, but from a toy’s perspective it becomes a landscape of endless possibilities: living room mountains, kitchen canyons, hallway race tracks. The central premise is the classic “toys come to life when humans aren’t looking” conceit, given a vehicle-focused twist. Each short episode follows Tom and his friends as they respond to a small problem—a lost friend, a broken toy, a sudden obstacle—using the wide variety of Tomica cars at their disposal. The stories emphasize teamwork, creative problem-solving, and the joy of imaginative play.

Notable narrative arcs appear in the transition between seasons. The first season, which began airing in July 2025, established the core cast and the rhythm of night-time escapades. The second season, premiering in July 2026, introduces a more frequent weekly format and an original theme song, signaling a deepened story world. Throughout, the tone remains gentle and optimistic, reflecting creator Tsumupapa’s signature warm illustration style and slice-of-life sensibility. Every adventure reinforces the simple wonder of what toys might do when no one is watching.
