Performing various experiments with Hoodsey; committing antics on Blake
Carl Foutley is Ginger's younger brother. He is in the fourth grade in the first season. He and his sidekick, Hoodsey (Tress MacNeille), come up with their schemes and perform their experiments in an abandoned doghouse in the Foutleys' backyard. The doghouse once belonged to the Foutleys' dog Monster, who ran away many years prior to the beginning of the series. In the series finale, Monster returns to the Foutleys. Because of his unique, yet disturbing personality, his family sometimes act like they don't like him, and often criticize him. His mother often claim's that she is also afraid of what he is planning.
Courtney Gripling's younger brother, Blake, is often the recipient of Carl's bad humor, due to the repeated theft of a petrified eyeball that initially belonged to Carl. Blake can usually be seen trying to get on Carl's good side, but Carl refuses his advances and takes every opportunity to humiliate Blake.
Carl's catch phrase is "classified." He is incredibly secretive about his plans, revealing as little as possible about them to anyone who may inquire, even if he needs outside help acquiring the necessary materials to carry them out, of which include catching a naked mole rat, turning himself into a wolf and attempting to stay on a ski lift for over 3 hours.
Despite his love of the gross and unusual, Carl's also got a big heart, as shown on several occasions; delivering a beautiful eulogy at Maude's funeral (Carl & Maude), and even openly crying after hearing about Mrs. Gordon's untimely passing hours after he'd tried to get her to return. In one episode "Fast Reputation," it was actually revealed that Carl is a great cook. Joann Bishop (Dodie and Hoodsey's mother) does not like Carl and often speaks very ill of him, despite his usual attempts to be nice to her.Carl's one true love is Noelle Sussman (Emily Kapnek). Originally, Noelle was viewed by Carl as a nobody on whom he could test his "disappearing powder", as he felt that she was expendable and would not be missed. As he studies the progress of his experiments, however, he realizes what a truly weird girl Noelle is, and that he misses her, leading the two to develop a relationship in And She Was Gone.
The series finale shows Carl and Hoodsey becoming popular TV reporters. They are also among the group at a reading of Ginger's latest book.
