 The style developed almost accidentally, with Povenmire's first sketch of title character, Phineas Flynn, which he produced while eating dinner with his family in a restaurant in South Pasadena, California.He doodled a triangle-shaped child on the butcher paper covering the table.He was so taken with sketch he tore it out, kept it, and used it as the prototype for Phineas and as the stylistic blueprint for the entire show.
