CJ is the oldest son and the second oldest child of the Casagrande siblings. He also has Down syndrome.
Personality
Carlos Jr. has Down Syndrome, which is exhibited through his childlike actions and lack of physical development, while in his teen years. He loves to play children's games like pirates and superheroes, and he can easily befriend any person, like Lincoln.
Carlos Jr. is also surprisingly perceptive. Many times, he notices things before other members of his family. For instance, when Lincoln and Lori come to visit the Casagrandes, CJ is the first to notice that they have arrived, as the other members of his family are all distracted with their own tasks. On another occasion, when the family notices Ronnie Anne is standing under an air conditioning unit, CJ is the first to realize the danger that the air conditioning unit might fall on her. He is also the first one to notice that he has been sprayed with pickle juice in "Pranks for the Memories with the Casagrandes".

Appearance
Carlos Jr. is a portly and stocky Mexican-American teenage boy with black scruffy hair. He wears a yellow shirt, a black bow tie with red outlines, dark blue shorts, white socks and blue shoes with green laces. Due to his disability, despite being 13 years old, where most kids have already or are just starting puberty, CJ is very short in stature. Due to Down Syndrome, he has small eyes that are further apart.
