Sonia Walnuts

Sonia Walnuts was the wife of Willy Walnuts, and the mother of Edith and Mila Walnuts. She died in a plane crash during her life as a flight attendant before Edith got pregnant. She is voiced by guest star, Lupe Ontiveros. Throughout the series, Sonia is seen in flashbacks and as a ghost.

Early Life
Sonia was born in Mexico during 1949. As she grown up, she moved to America to become a flight attendant/stewardess where she met Willy Walnuts, they fell in love, got married and gave birth to Edith and Mila.

Death
On Christmas Eve 1981, during her job as a flight attendant, Sonia decides to go home and be with her family. Unfortunately, a bad storm was rough and loud. Due to a faulty engine, the pilot/co-pilot is unable to navigate through the storm, and as a result, they crashes into a mountain (in the USA), and Sonia is killed instantly (on-screen).
