Miguel Fibs! is about a little boy who has a reputation of being very good. Everyone, including his mother, father, and teacher, sees him as a very good little boy. He knows it is expected of him so he wants to be good. However, rather than to erase that image, he tells fibs to cover up that he is not always good. Then, his conscience starts to bother him, and he imagines seeing images in the mirror and becomes afraid. After a long period of worry, he confesses to his parents about his lies, explaining that he is not a good boy. His parents warmly explain that all people are bad sometimes and assure him that he is most certainly still a good boy.
