It took me FOREVER to get this to Sylestia from my iPad's photos...
I call it Hypinomouse, a combination of Hypnosis, Albino (Because they are white), and obviously, mouse.
The description in the pets list:
These adorable-eyed mice Sylestis may be cute, but looks can be deceiving. Females are super tough, and will hypnotise anyone who tries to get into their territory. But how does this hypnosis get intruders out? Well, the victims will be hypnotised into jumping off of the cliffs that these Sylestis call home. Males are far kinder, but when they try to calm down the females, the males often get hypnotised like intruders. However, They like living on short cliffs, so while injuries may be obtained, those who fall victim to the hypnosis rarely die.
Sorry for the long description, but I wanted to get every detail about them out of my mind and into yours.
Enjoy! Oh, and if this becomes a real pet, I'm gonna SCREAM! (In happiness, of course!)

I dont see your picture but from the description it look preaty cute ^-^
