In "Oryx and Crake," Crake explains the mating behavior of male frogs, who produce loud calls to attract females. The depth and volume of their croaks indicate strength and genetic superiority, making them more appealing. Interestingly, smaller male frogs have been observed using empty drainpipes as makeshift amplifiers, boosting their calls to seem more formidable than they truly are.

This metaphor extends to art, which Crake likens to the empty drainpipe for artists. Just as the small frogs use the pipes to enhance their mating calls, artists use their work as a means to express themselves, gain recognition, and connect with others, suggesting that art functions as a powerful tool for attraction and communication.
