However, there are a few instances related to snakes that could be considered:
* Nagini: Although not directly mentioned, Nagini is likely present alongside Voldemort throughout the book, making her a lingering presence.
* Parseltongue: Harry's ability to speak Parseltongue, the language of snakes, is further explored and becomes relevant to the plot.
* Symbolic Significance: The presence of snakes and their symbolism, especially in relation to Voldemort and Harry's connection to him, are still relevant themes in the book.
Overall, while snakes are not physically present as characters in the book, they are still an important underlying element connected to the plot and characters.
