Tojo in cub colors with his parents for a color compare.

Sanura is an OC. She's Mufasa's best childhood friend and the only lioness he had a cub with aside from Sarabi. Had Uru never brought Sarabi to the Pridelands, Sanura likely would have been queen. Tojo gets his blond from her side of the family. King Mufasa in his daylight colors.
