Here is the production process.
Notes: It takes 10-11 months to make an eleven minute episode. Also the writers submit premises and outlines for stories; They don't write the script. Also, they have to send the story ideas to Nickelodeon for approval.
1): Once a premise is approved it goes to the storyboard directors who write the dialogue and draw the picture.
2): In other words, the storyboard follows dialogue, action, and sound effects. But before the storyboard stage, Banks and the three writers who work under him must create stories and "pitch" or present them to the co-cxecutive producer, Paul TIbbitt.
3): Once the animation is completed and approved, they are sent to Korea; where the animation is accordingly done. When it is complete, it is sent back to the studio, and Paul Tibbit decides where the music and sound effects be. He turns it over to Nick Carr, who selects the music. Sound Effects is added last, the final mix is done, and the show is finished.
