Rana

"Rana" were mobs who resembled little girls with frog hats. They were originally  in-game as a test; Rana was made by "Dock", Minecraft's past artist,  for another project of his. The player's character was supposed to look like Rana, albeit with a miner hat, no ponytails and a different skin. This was scrapped with Dock's removal, with a fair few people arguing for her to stay. There were also other mobs that were styled like Rana, called Steve, Black Steve and Beastboy. however, these were pulled from the game at the same time as Rana.

Drops
Rana never dropped any items in her short existence, and nor did any other of Dock's characters
