This is Raz Mah Tazz, or Raz for short. Or, if you're a close friend, Razzle.
Their species is called repture. Repts is plural.
They are androgynous in this picture, but can be any gender.
Their favorite food is anything edible.
They are very tasty, making them a well enjoyed snack.
The handle of their tail makes them noticeably easier to catch, when not held.
