Monica's Gang/Heartwarming


 * Chuck Billy's one-time little sister, Mariana, who was in fact a star that came down to Earth as a human baby born from his mother. However, she died very early in her life, and thus turned back into a star and returned to the sky. Since then, she has always watched over her human parents and brother and, in one of Chuck's birthdays, she was authorized to come down from heaven to give him a gift:
 * This.
 * And this scene from one of the movies (see The Movie), which doubles as a Tear Jerker.
