In "The Battle of the Labyrinth" by Rick Riordan, Percy and Annabeth discuss a mythological group known as the Hundred-Handed Ones. Annabeth explains that they are the elder siblings of the Cyclopes and earned their name due to their appearance, which features a remarkable hundred hands. This highlights their extraordinary nature and significance in mythology.

Tyson expresses excitement, emphasizing the immense strength and height of these beings, suggesting they possess the power to break mountains. Percy's witty response adds humor to the conversation, acknowledging the awe-inspiring qualities of the Hundred-Handed Ones while also pointing out that their strength could spell trouble for mountains themselves.
