Somewhat terrible, but bearable.
Plot: Todd, Riley, are siblings in an orphanage. They saw an ad from a comicbook, or a magazine, a cell phone that can be used to call an replacement. They replaced their parents and anyone they dislike. (Somewhat spoiled, isn't it?)
Characters: Their personalities are mostly in wrong position. Voice actings are mostly unfitting. Riley and Todd are spoiled brats.
Humor: Nothing, except being silly to the full point. Like they have an IQ of a monkey. That's not that funny.
Art: Fair, like a typical cartoon would do. Animation is also fair.
Overall: 2. I just don't like the plot and the characters, and also the humor. It only shows some annoyance from their bad attitudes and traits.
