Doraemon

Nobita is scolded by his mom for napping instead of doing homework, and wishes for a tool like in fairy tales that can do work while he sleeps. Doraemon gives him the “Little Helper Box,” which summons tiny robots to complete any task requested before sleeping. Nobita first tests it with small chores like polishing shoes, and the robots successfully complete everything. Encouraged by this, he starts using the box to help others with increasingly larger tasks, gaining praise and confidence, but eventually becomes overconfident and takes on too many requests.
