However, as the story progresses, Squid, like many of the boys at the camp, undergoes character development.

As the boys face the hardships and mysteries of Camp Green Lake, including digging holes in the dry lake bed as part of their punishment, they develop camaraderie and friendships. Squid is no exception, and he eventually becomes a more sympathetic and likable character as the story unfolds.

The character Squid is a part of the ensemble cast of young inmates who each have their own backgrounds and stories to tell in "Holes," contributing to the novel's themes of friendship, perseverance, and redemption.
