The poem emphasizes the hippo's comical aspects, poking fun at its large size, its insatiable appetite, and its apparent laziness. Nash describes the hippo's "muddy bulk," "gruesome smile," and "river bed appetite," highlighting the animal's unwieldy nature and tendency to wallow in mud. The poet also emphasizes the hippo's lack of grace, noting how it "trots along unfeelingly," creating a humorous contrast between its massive appearance and its rather clumsy movements.
Moreover, Nash uses wordplay and rhyme to add to the poem's comedic effect. For instance, he describes the hippo's yawn as "titanic" and its teeth as "tusky white." These playful descriptions, combined with the rhyming scheme, create a lighthearted and entertaining tone that invites the reader to join in the amusement.
While the poem focuses primarily on the hippo's physical characteristics and behaviors, it also hints at deeper meanings. The hippo's "hide of India rubber," for example, could be interpreted as a symbol of resilience and adaptability. Additionally, the poem's closing line, "And therefore has the hippopotamus/ His slightly supercilious air," can be seen as a commentary on the hippo's self-assurance despite its unusual appearance and habits.
Overall, The Hippopotamus is a clever and amusing poem that offers a lighthearted take on the animal kingdom. Ogden Nash's humorous observations and playful language make the poem both entertaining and memorable, encouraging readers to appreciate the peculiar charm and eccentricities of the hippopotamus.
