3. It

It began in a pond in the swampy area outside of Undercover. It grew up as a solitary hillspawn and puppy, and soon found it had a remarkable talent for finding eggs of keke who looked exactly like it did - same eyes, same skin, same scales. And so it began collecting its friends. These friends now form the Numbskull Nest, after the others realised the talent of finding more like them extended to them all, and not just it. It, however, is seen as a strange mix between the family dog that constantly needs to be watched, and the eldest sibling.
