Reason: This mob is actually the same mob as the Human, just that the model was changed during Indev before becoming the Human again. (The Human page itself is pending a split, though, so it'd be better to wait and then merge this into either Mob or Monster, depending on which entity it corresponds to.)
Rana spawned randomly in the world in groups with other Ranas. They could spawn at any light level as long as there was enough space.
Rana was a passive mob. It had no animation, so it aimlessly glided and jumped around the world in the same, still pose, and never stopped moving around. Rana, along with Beast Boy, Steve, and Black Steve acted in this identical manner. Depending on the version, upon death, Rana would not fall over to the ground or flash red or white and appear to die, as most mobs do. It would just disappear shortly thereafter, and drop no items or the items it was designated to drop.

- Rana was created by Dock for a project of his own years ago. When he joined the Minecraft development team, he recreated her in a new style for the game as a test. She was never intended to be a permanent addition. 
- Rana means "frog" in Latin, and, through linguistic evolution, Spanish and Italian.
- Rana is actually the name of a genus including 50 to 100 extant species of frogs, commonly known as Holarctic true frogs, pond frogs, or brown frogs.
A part of a sketch Dock made of Rana. The full image wasn't archived, but the link name indicates that it had Rana standing in a puddle. This was a redesign from the original character.
