I REALLY want to make them official, so I will! I might even write a fanfic about it... andyways here is the story line:
-----------------------------------------------------
Simba looked down at his other cub, Jasmine. He was spending some time with her as Zira was out hunting. She was very muuch a mummys girl and Simba wanted the best for his daughter. She had the same mark on her head as her mother, and bright blue eyes. She was beautiful. "Daddy, when will mom be back?" She asked eagerly. "I don't know, Jasmine." Simba replied. Zira came up to them with antelope that very moment. Jasmine dug in, eager for her food. Simba smiled. His cubs weren't so bad after all.
-----------------------------------------------------
OK, I tried to make Jasmine's main colour a mixture of Simba and Zira's colours, but I did not use a special program. My secrets shall not be revealed, mwahahaha
