Squid's real name is Alan. I'm not sure he has a last name.
alan
Because his real name is Alan Rex then his last name and Rex in pig latin is X-ray. (I found that out for a college assignment when I had to read the book "Small Steps". it is by Louis Sachar and is kind of like a Sequel to holes.)
The title of the book refers to holes the boys dig in the book.
In the book "Holes" by Louis Sachar, Alan gets the nickname "Squid" because of his habit of squirting his toothpaste onto the bedposts of his bunk. This behavior resembles a squid squirting ink, hence the nickname. Additionally, Alan's real name is not revealed until later in the story, adding to the mystery and intrigue surrounding his character.
