Annoying Orange: Theme Song Attack! is the fourty-sixth episode of the Annoying Orange series. This episode features theme songs for characters.
The episode starts with Orange, Midget Apple and Marshmallow all trying to think of a word that rhymes with Orange. Midget Apple thought of one until Orange refuses. Pear asks what's going on and Midget Apple tries to think about some words that rhyme with "Orange". Pear is shocked about Orange having no theme song because everyone else has a theme song. Marshmallow says that rainbows are wonderful, Orange thinks of the word "no" and then Pear's theme plays. Orange wows at him because of his theme song. Pear then replied that Midget Apple has one as well, too. After that, Pear states that Marshmallow also has a theme song. Orange wonders if a fruit on the other end of the counter, Plum, has one too and Plum indifferently replies, "Yep. I sure do." and his theme song plays. Orange tells Plum that one word about hearing about his theme song is Knife and not only makes Knife's theme play, but also accidentally gets Plum minced and taken away while Orange, Pear, Midget Apple and Marshmallow are screaming until they all stop. Orange still thought about his theme song that hasn't been created until Marshmallow helps him write his theme song and the theme song plays.
The episode ends with Orange asks Marshmallow about his addiction with rainbows and Marshmallow cries out "Rainbows are wonderful!" with Orange grunting.
