Camp Green Lake •
Stanley Yelnats IV (also known as "
Caveman" by the rest of the campers): Stanley is a 14-year-old boy who did not have any friends at school and was often picked on by his classmates and
bullied due to being overweight. Stanley's family is cursed with bad luck, and although they do not have much money, they always try to remain hopeful and look on the bright side of things. Stanley shares these traits with his family and, although he does not have a lot of self-confidence, he is not easily depressed, a characteristic that helps him adjust to the horrendous conditions of Camp Green Lake. However, he has a habit of blaming his great-great-grandfather when he gets in trouble. As the book progresses, Stanley slowly gains strength. He identifies the people who threaten him, like the Warden. While he tries not to get in trouble, he also stands up for himself and his friends and family. Stanley rebels for the rights of his friends when he steals Mr. Sir's truck to look for Zero in the dry lake bed. •
Zero (Hector Zeroni): Zero is known to be the best digger and is the smallest and youngest inmate at Camp Green Lake. He is considered to be stupid by the other boys and the counselors alike since he does not often speak due to the fact that he is wary of those who mock him. He is said to always have a scowl on his face and does not like to answer questions. He lacks an education, meaning he is unable to read or write. Despite this, he is intelligent and manages to stand up for himself in the face of adversity, breaking Mr. Pendanski's nose with a shovel after one too many snide remarks. Zero is shown to be an honest character after becoming close friends with Stanley. Zero is the one who stole the shoes that Stanley was arrested for and accused of stealing. He is the descendant of Madame Zeroni, the woman who put a curse on Stanley's family. He has been homeless for most of his life, as well as getting separated from his mother at a very young age. Although he suffers quite a bit, he always seems to persevere and he has a happy ending. •
X-Ray (Rex Washburn): X-Ray is the unofficial head of the boys in Group D, who was sent to Camp Green Lake after he was caught selling dried herbs to people who thought they were buying
marijuana (as revealed in the spin-off novel
Small Steps). His nickname X-ray comes from it being
pig Latin of his actual name, Rex. X-Ray maintains his position as the leader of the boys even though he is one of the smallest and can barely see without his glasses. X-Ray is able to maintain his position at the head of the group through a system of rewards and allies. Every time Stanley does something nice for X-Ray, X-Ray rewards Stanley. He stands up for Stanley when the other boys pick on him (i.e, X-Ray decides Stanley will be called "Caveman" and moves him up one spot in the line for water). When Stanley becomes friends with Zero, however, X-Ray's hierarchy is threatened and he becomes hostile toward Stanley. •
Squid (Alan): Squid is a member of Group D at Camp Green Lake. Often, he taunts Stanley for sending and receiving letters to and from his mother. Squid is very tough but subservient to X-Ray's rules. He is revealed to have a sensitive side to him, however, when Stanley wakes to hear him crying one night. Alan later asks Stanley to write to his (Alan's) mother when Stanley leaves Camp Green Lake. •
Armpit (Theodore Thomas Johnson): A member of Group D. Like the other boys, Armpit is rough, shoving Stanley to the ground when he calls him Theodore. However, in the
Holes spin-off novel
Small Steps, he is shown to have become hardworking and caring. His nickname Armpit is due to him being stung by a
scorpion at camp and the
venom traveling up into his armpit, causing him to complain about his armpit hurting. •
Magnet (José): Another member of Group D. Magnet earned his nickname because of his ability to steal and refers to his fingers as "little magnets." •
Zigzag (Ricky): Described as being the tallest kid of Group D, constantly looking like he has been electrocuted, with frizzy hair. Stanley often thinks he is the strangest camper at Camp Green Lake. Zigzag hits Stanley on the head with a shovel, but later apologizes. Zigzag suffers from
paranoia, highlighting his displayed "craziness". •
Warden (Louise Walker): Running Camp Green Lake, she is soft-spoken but intimidating. Known to be violent and abusive, she uses her power and privilege to get what she wants and make members of the camp do as she pleases. She is often thought to have hidden cameras to spy on the campers, including in the showers, causing Stanley to be paranoid whenever he takes a shower. She wears
nail polish laced with
rattlesnake venom, and scratches Mr. Sir when he displeases her. She has the members of Camp Green Lake dig holes to look for Kate Barlow's hidden treasure. She is the granddaughter of Trout Walker. Her family had been digging the treasure out since her birth, but to no success. She is known for her catchphrase, "Excuse me?". •
Mr. Sir (Marion Sevillo): The overseer/head counselor at Camp Green Lake, below only the warden. He is constantly eating sunflower seeds after quitting smoking. He is rough, tough, and tyrannical, embracing his meanness and enjoying asserting his power over the boys. However, his cowardly nature is revealed when he encounters his biggest fear, yellow-spotted lizards. He also watches his words around the warden, the only person more powerful than him. While his backstory is never told in the book, his true identity is revealed in the film as a paroled criminal named Marion Sevillo, who was arrested for an unknown crime in El Paso, and later violated his parole by carrying a gun. •
Mr. Steve Pendanski: Mr. Pendanski is the counselor in charge of group D at Camp Green Lake. Mr. Pendanski has a generally friendly demeanor, yet is just as cruel as the Warden and Mr. Sir. His darker side comes out in his frequent mistreatment of Zero, as well as in his callous lack of concern when Stanley and Zero are covered in deadly yellow-spotted lizards. Zero attacks Mr. Pendanski with a shovel. In the film, he is addressed as "Dr. Pendanski," though he is revealed not to be a real doctor.
Town of Green Lake • '''Katherine Barlow (Kissin' Kate Barlow)''': Katherine Barlow is a sweet and intelligent woman who teaches in a one-room school house on Green Lake one hundred and ten years before Stanley arrives at Camp Green Lake. She falls in love with Sam, an
African American man who sells onions in the town. Although the rest of the white people in the town are
racist and enforce rules that
prohibit African American people from going to school, Kate, who is white, does not care about the color of a person's skin and she loves Sam for the person that he is. When Kate and Sam kiss, the angry townsfolk kill Sam and destroy her schoolhouse. Kate is devastated by Sam's death and becomes Kissin' Kate Barlow, one of the most feared
outlaws in the West. She leaves her mark by kissing the bodies of the men she killed; if she had only robbed them, she would leave them in the hot desert. She is the outlaw responsible for robbing Stanley Yelnats I (Stanley's ancestor). After she is confronted by Charles "Trout" Walker and his wife Linda, who demand to know the location of her buried loot, Kate is bitten by a yellow-spotted lizard, and dies laughing, knowing the Walkers will never find her treasure. The lipstick tube that Stanley finds during his second week at Camp Green Lake was owned by Kate. •
Sam: Sam is an African-American farmer in the town Green Lake, Texas who grows onions. He believes onions are the cure to everything and makes many remedies from onions. He also has an immense love for his
donkey, Mary Lou. His relationship with Kate begins when he exchanges his onions for her jars of spiced peaches. He is shot in cold blood by Charles "Trout" Walker when Sam and Kate try to escape. His death is implied to have set a curse upon the lake, causing the rain to stop coming and the lake to dry up. •
Charles "Trout" Walker: Charles "Trout" Walker is an extremely spoiled son of the richest family in Green Lake. He gets upset when Kate denies his wish to court her. This adds on to the reason of him leading the townspeople to burn down the schoolhouse and kill Sam. His nickname Trout comes from his foot fungus that causes his feet to smell like dead fish. After Kate leaves to become an outlaw, he marries Linda Miller but his family loses everything when the lake dries up. He is the Warden's grandfather, who, upon his death, opens up the
juvenile detention camp to increase the efficiency of finding Kate Barlow's hidden treasure. •
Stanley Yelnats I: Stanley Yelnats I is the son of Elya Yelnats as well as the great-grandfather of Stanley Yelnats IV. He had his treasure stolen by Kate Barlow while he was moving from
New York to
California. He is known to have survived by climbing to the top of a thumb-shaped mountain (God's Thumb) which happens to be Sam's old onion field.
Mid-1800s Latvia •
Elya Yelnats: Elya is the great-great-grandfather of Stanley. He is often referred to as his "No-good-dirty-rotten-pig-stealing-great-great-grandfather", constantly being blamed for everything that goes wrong in Stanley's life. He is considered to be the reason why the Yelnats family has such bad luck. As he sets off for America, he forgets to fulfill the promise he made to an old woman named Madame Zeroni. This causes generations of bad luck to trickle down the Yelnats family tree. However, he does pass down an important song that Madame Zeroni taught him in Latvia, which breaks the curse. •
Madame Zeroni: Madame Zeroni is the great-great-great-grandmother of Hector Zeroni (Zero). She is great friends with Elya Yelnats, and she gives him a pig to help him marry Myra Menke. Because Elya breaks his promise of carrying her to the top of the mountain, she is considered to be the one who put a "curse" on the Yelnats family. •
Myra Menke: Myra is the most beautiful girl in the Latvian village Elya lives in. Madame Zeroni considers her inadequate and her head as empty as a flowerpot. Myra's father promises to award her hand in marriage to whichever suitor can raise the fattest pig. When the pigs offered are the same size, Myra asks Elya and Igor Barkov to guess a number between 1 and 10, showing her inability to make her own decisions. Upon realizing this, Elya allows Myra to marry Igor. •
Igor Barkov: Igor is Elya's competitor for the hand of Myra Menke. He is an old, fat, successful pig farmer.
