Acidity

Acidity was right away known to be odd when her mother was carrying her egg, and then suddenly dropped it in a pool of acid nearby. The egg was completely unaffected, and the acid just slid off of it as if it had never been in the acid at all.
When Acidity hatched, she was just like any spiral: energetic and playful. With a very cliche name as well. However, at the same time, she seemed to be mischievous, but not malicious, in a manner and would pop out of liquids to scare people without a single clue of her being there. It was quite the anomaly, to be certain.
Her parents finally decided to find someone who could explain why she could do the things she did, including the time she was an egg. They took them to every healer, elder, and scientists... but none of them could explain her unique ability.
However, the last scientist they visited, Nirvana, knew who could tell them.
She took her to ms. Caerwyn, who could right away tell she was peculiar. Thus, she took the hatchling in, making her safe.
(((Add on to this! Who adopted her? Why? Who are her friends? Foes?))
