All of this foolish behavior, especially the Which's, can be linked to the disappearance of Rhyme and Reason from the land. Juster frequently returns to this theme as Milo encounters a number of nonsensical characters throughout the book. The author's message is that of simple common sense: each of these characters has lost his or her understanding of the obviously right thing to do.

It is also significant that Milo begins his friendship with Tock, the watchdog, in this chapter, as it represents an important turning point for Milo. Though Milo certainly has a lot to learn, his biggest problem was his boredom and laziness. Tock saved him from that in the Doldrums by getting him to use his imagination, and the fact that he continues to accompany Milo suggests that Milo has conquered this problem altogether. In the rest of the book, Milo will deal with a number of his shortcomings, but never again will he appear to be the dull little boy he was in Chapter 1. His immediate friendship with Tock suggests that he has the watchdog to thank for it.
