When Angelica splatters her room with paintin a fit of anger, Charlotte tells the mess a work of art and hires Angelica to redecorate Chas' den. When the adults react favorably to this as well, Angelica is entered into an art contest. But will the judge of the contest be as impressed when her methods are revealed? - Description from Klasky Csupo
Angelica apparently has real talent as an artist. However, not everyone thinks that is so. In addition, her "talent" has a hidden secret.
When Angelica says "Come on" when Chuckie is hesitating into decorating Chas' den, her teeth are miscolored pink instead of white.
In the shot where Didi first appears, she isn't wearing her lipstick.
Chuckie is seen in the art fair coloring a book with his right hand despite the fact that he's left-handed as seen in a later episode, "Chuckie's a Lefty".
