Tomica to Tom (TV)

When people fall asleep or leave the house, Tomica cars and Tom do not simply remain where they were left. Out of human sight, a secret life begins—tiny roads, unexpected adventures, and mishaps that could only happen in a world the size of a toy box. Before their owners return, Tom and his friends have to put everything back exactly as it was... or at least close enough that no one discovers what the toys have really been doing.
