I had heard rumors of the ghostly hydra, ghostly crocolisk, and oozeling, but I had wanted to wait until rumors had been confirmed.
Petopia has verified that these three anomalies do exist. Article here, info on how to tame
The thing is, these three creatures all fancy themselves crocolisks. This makes sense for the ghostly croc, but the hydra and ooze are a mystery. I would add these to my page, but I doubt they will last long once that start getting attention.

Let the Hunt begin!
