Song Meaning
The lyrics paint a picture of anxious anticipation, centered around the recurring image of "blue rats." The repeated phrase "what's the matter?" coupled with the onomatopoeic "pitter-patter" establishes a tone of unease and a sense of something small and persistent approaching. This isn't a literal infestation, but rather a metaphorical representation of an impending, perhaps unsettling, event or feeling.
The core of the song lies in the narrator's passive waiting for a "scratch." This action, "scratch," is amplified in the refrain, becoming the focal point of the narrator's attention. The repetition of "scritch, scratch" suggests a building tension, a persistent, almost irritating sensation that the narrator is bracing for. It's a sound that signifies either an arrival or a disruption.
The deliberate ambiguity of "blue rats" is key to the song's effect. They are not described as menacing or dangerous, but their color and the sound they make – "pitter-patter" and "scratch" – create a unique, slightly off-kilter atmosphere. The narrator's singular focus on waiting for this "scratch" implies a deep-seated expectation, as if this particular sensation is inevitable and significant, even if its meaning remains unclear.
Ultimately, the effectiveness of these lyrics stems from their minimalist approach. By focusing on a strange, evocative image and a singular, repeated action, the song creates a potent sense of suspense and internal unease. The listener is left to ponder the nature of the "blue rats" and the significance of the "scratch," mirroring the narrator's own state of unresolved anticipation.
