Carl Karl

, nicknamed Dr. Coconut by Dr. Doofenshmirtz, is the hapless intern and cameraman of Major Monogram. He is a rookie and is very loyal to Major Monogram. He works at the[O.W.C.A. for college credit.

Biography
When Dr. Doofenshmirtz asked Vanessa to pick up blueprints at Blueprint Heaven for a Space Laser-inator Ray, Carl is dressed as the lady at Blueprint Heaven. He accidentally gives real plans for a Space Laser-inator Ray to Ferb and gave Vanessa the blueprints for an Ice Cream Machine. Major Monogram then calls him a rookie for his mistake ("I Scream, You Scream").

When Major Monogram is unable to debrief Agent P due to a back injury, Carl does it instead. He made the close-up too close to his face, making his glasses the only thing visible ("The Flying Fishmonger").

When Dr. Doofenshmirtz built the Freezeinator, it was Carl who debriefed the mission instead of Major Monogram due to the Major being unable to move because he was shot by the Freezinator. He accidentally knocks Major Monogram over, thus showing that he is very clumsy ("It's About Time!").

Carl also has his own theme called, Carl, the Intern. He once had to disguise himself as an ice cream man because Baljeet and Buford were watching Perry and Perry couldn't get his mission. So when Baljeet and Buford were ordering Carl's ice cream, Perry went through an escape door in the ice cream truck. Then Carl zooms off, leaving Baljeet clueless about where Perry went ("Swiss Family Phineas").

During the Father-Daughter picnic, he built a robotic replica of the Flynn-Fletcher family to replace Lawrence Fletcher for the Father-Daughter picnic competition while he restoring his memory. He also help make the switch the robotic version and the real Mr. Fletcher and congratulates Agent P until a kid sees them, forcing him and Agent P to quickly leaves the scene ("I Was a Middle Aged Robot").

When Phineas and Ferb create a device to reverse the effects of gravity, Carl goes undercover as a boy, thinking that Phineas and Ferb are in league with Doofenshmirtz. Since Agent P is close to the boys, Major Monogram has him find Agent G, giving him suspect locations, some being the moon and Monte Carlo. Carl discovers that the boys are just having fun and returns with the news ("Undercover Carl").

When Dr. Doofenshmirtz abducts Major Monogram, Carl gives Perry his briefing, describing Major Monogram going to Tokyo for the international Good Guy convention. He also shows the letter made from cut-out magazine letters, and mentions Dr. Doofenshmirtz going to Tokyo with his daughter. However, he passes the whole situation off as a coincidence, and gives Perry the day off ("Phineas and Ferb Summer Belongs to You!").

Personality
Carl is a bit careless and sometimes forgets to focus the camera, causing Major Monogram to be humiliated during some occasions. In one occasion in particular, Carl accidentally didn't zoom in, revealing that Major Monogram isn't wearing any pants. He is also desperate for a girlfriend. When Agent P went into his lair while his brain was in Candace Flynn's body, they at first thought there had been a breach in security and that it was a real girl, causing Carl to get very excited. They are soon under the impression that it was merely a disguised Agent P when his fedora falls onto his head. Carl was very disappointed, he walked off-screen dejectedly, saying, "Man! I thought it was a real girl" ("Does This Duckbill Make Me Look Fat?").

Background Information

 * His full name was revealed to be Carl Karl in the credits of "Ain't No Kiddie Ride". Prior to that, he was listed as "Karl" in the credits for most of his appearances, and his name was shown on-screen as "Carl" in "Swiss Family Phineas". (See the logo in the picture above.) Carl Karl is also used in the "Gelatin World" commercial for the Phineas and Ferb: Across the 2nd Dimension video game adaptation.
 * He drives an undercover ice cream truck ("Swiss Family Phineas", "I Was a Middle Aged Robot").
 * Major Monogram calls him a rookie. This might mean that he might have started working there at the beginning of summer ("I Scream, You Scream"). This belief is contradicted in "Phineas and Ferb: Across the Second Dimension", as it shows Carl secretly assigning Perry to the Flynn-Fletcher family 5 years in the past. Or it just meant that Carl has been working for Monogram for about 5 years as some sort of volunteer and has only been promoted to 'unpaid intern' that summer.
 * Carl's age is not certain, but he is most likely a sophomore going to be a junior next school year, as he said "he based his sophomore thesis on quakes and seismic events" ("At the Car Wash").
 * He knows how to cook a spaghetti, but his forgetfulness prevents him from cooking it well ("At the Car Wash").
