"Baby-Faced" Carlton Ulysses "Carl" Wheezer is one of Jimmy's best friends. According to canon, he is currently 12 years old.



Carl likes to eat, and this caused him to be overweight. When his parents expanded their cable line-up, Carl found himself focusing on a channel devoted to llamas and a show about a superhero called Llama Boy the Super Hero. He has adored llamas ever since, going so far as to join a fan club, the Llama Love Society (Which he likely created as he is shown to be the first member). He once turned into a llama. He is allergic to almost everything.

It is revealed in "The Incredible Shrinking Town" that he took ventriloquist lessons, and that he can virtually imitate and sound just like everyone. It is also a hinted that he has some sort of dislike for Sheen, even though he's one of the his two best friends. Carl enjoys playing a video game called Llamapalooza.

It was stated by himself that he as always wanted to touch a Llama in the Jimmy Neutron: Boy Genius Movie.



Carl has peach skin and many freckles. He has a pair of small black eyes and red hair. He often wears an orange-and-red striped shirt, a pair of green pants (shown with suspenders in the movie), a pair of brown loafers, and glasses.
