While Spring cleaning in the middle of November, Billy takes an old, cursed lamp from Grim's trunk. When he gives it a rub, he releases the curse Grim had warned them about: his own mother. Having three wishes to make, Billy wastes his wish by wishing to know what to wish for. Mandy wishes Billy and Grim would "shut up", so Grim never gets to make his wish. Then, Mandy decides to make the last wish to whoever makes her the happiest. In the end, Mandy wishes everyone in the world would go away, which she is glad about.

Billy y Calavera se encuentran con Miriam, la madre de Calavera al frotar una lámpara mágica y esta le concede un deseo a Billy, pero cuando llega el turno de Calavera, Mandy se aprovecha y toma su deseo y desea que él y Billy no puedan hablar, y si ellos quieren un deseo, tendrán que hacer feliz a Mandy.
