There are a few possibilities why you might be asking about this:
* Misunderstanding: Perhaps you're thinking of something else entirely. Could you provide more context? Maybe you're thinking of a specific quest, an item with a similar name, or a specific faerie.
* Fan Creation: The term "Tears of Water Faerie" could be a fan-made creation for a story, a game, or a fan wiki.
To help me understand your question better, please tell me:
* Where did you encounter this phrase? Was it in a guide, forum, or another part of the Neopets website?
* What do you think the "Tears of Water Faerie" are? Do you have any idea what they're used for or what they look like?
With more information, I can hopefully provide a more accurate answer!
