Rocky the Rhino is a visually-challenged rhinocerous character who was dropped from the 1967 film The Jungle Book. He was to appear in the vulture sequence and would have been voiced by Frank Fontaine. He was to be animated by Milt Kahl before the character was ultimately dropped from the story.
Many of Rocky's traits were recycled into the Rhino Guards and executioner from Robin Hood. One of the guards even crashed into a rock failing to catch Lady Kluck, just like Rocky did in failing to attack Mowgli.
Some pictures show Rocky having a little bird friend. Not much is known about the bird, but it can be assumed to have served as Rocky's conscience, similar to Timothy Q. Mouse and Jiminy Cricket and that it was a Mynah, which is a bird seen feeding off of Indian Rhinos.
In Jungle Cubs, there are several rhinos that looks very similar to Rocky. One can be seen in Season One's intro and the episode "How the Panther Lost His Roar". Unlike Rocky, however, this rhino in the show was a threat to the cubs. In the episode "Splendor in the Mud", Winifred's herd encounters a mother rhino with a calf (possibly Rocky) that threatened the herd to get out of her way and knocked Winifred's uncle over. Another rhino resembling Rocky (only with a small, round jaw) shows up in "The Great Kaadini".
