In Richard Adams' novel "Watership Down," the character expresses concern about the influence of small, seemingly insignificant characters, referred to as "little Bigwigs." This highlights the idea that even the smallest individuals can hold power and significance, causing others to reconsider their positions. The quote emphasizes a sense of caution and respect for the unexpected potential of those who might appear minor.

The use of the term "tremble" suggests a kind of fear or respect for this potential, indicating that underestimating these small figures could lead to unforeseen consequences. The message serves as a reminder of the importance of acknowledging everyone's impact, regardless of their size or status in a community.
