"[6] While the children initially (and not entirely without merit) consider him a "wet blanket" who removes the good from any situation, he proves to be a strong and steadfast companion, especially in Underland where he is all they have to cling to.

It is Puddleglum who often spots the best course of action, and ultimately Puddleglum who wins the debate with the Lady of the Green Kirtle, breaking her spell and releasing the Prince by stamping out her magical fire (badly injuring his foot in the process, though not as much as a normal human would, since his feet are webbed).

Lewis is perhaps using Puddleglum to give a somewhat existential statement of faith when he writes, "Suppose we have only dreamed, or made up, all of those things—trees and grass and sun and moon and stars and Aslan himself.
