Here's why:
* Lack of Pronouns: The story focuses on the Pokémon's strange behavior and appearance, never using pronouns like "he" or "she."
* Ambiguity: The story intentionally leaves the Pokémon's gender ambiguous, adding to the unsettling and unsettling nature of the narrative.
Therefore, the gender of the "EEeEE" Pokémon is left to the reader's interpretation.
