Micaela is a little girl who loves animals and loves to draw and play with her many friends. Because she respects nature and is always helping people, she is called by the World of Fantasy, via the Tree of Knowledge, for an important mission. She gets a tough assignment from its King to foil the sinister plans of Dr. Black and his assistants, whose evil formula will change everything to grey and black. The only problem is: in order to complete her mission, she must turn into a cartoon! Micaela gains cartoon powers, like growing large and small, and helps her new friends to fight against the villain Dr. Black, who wants to take away the colors from everything in the world.
