The set gives each Gahlok Va one hook, on its left arm, while the BIONICLE Encyclopedia and its updated edition describe the unit as carrying twin hooks.

Nothing in the story gives the hook any elemental power. The Gahlok Va's own talents were climbing and swimming, and they moved in a way that looked sluggish but rarely stopped, so they covered more ground than they seemed to. (BIONICLE: Encyclopedia Updated)

The Climbing Hook is a small piece of a bigger pattern: every Bohrok Va was given a simple tool matched to the Bohrok it served, and the Gahlok Va's hook fitted a helper built for climbing. (BIONICLE: Encyclopedia Updated; Gahlok Va)
Frequently asked questions
- What was the Climbing Hook in BIONICLE?
- The Climbing Hook was the tool of the Gahlok Va, the Bohrok Va that worked alongside the water-aligned Gahlok. On the model, each Gahlok Va has a single hook fitted in place of its left hand.
- What was the Climbing Hook used for?
- Climbing. The hook helped the Gahlok Va, which were already good climbers and swimmers, get over the terrain they worked in.
- Did the Gahlok Va have one hook or two?
- The set has one hook, on the left arm. The BIONICLE Encyclopedia and its updated edition both describe the Gahlok Va as carrying twin hooks, so the books and the model don't quite agree.
- What happened to the Climbing Hook after the Bohrok swarms were stopped?
- The Gahlok Va went back into hibernation after the Bohrok-Kal were beaten. After the Matoran left Mata Nui, the Toa Nuva woke the swarms again to finish clearing the island, and once the job was done the Bohrok and their helpers returned to the nests.
