Not your Ordinary Family
I love this family so much!
I was listening to We are Family by Keke Palmer from the Ice Age: Continental Drift. I just thought it fit so well!
You have Timon who is the adoptive father of Simba, which makes him Kiara and Kion’s adoptive grandpa. Pumbaa who is the uncle (since he and Timon have a brotherly relationship) that Simba never had, which makes him the adoptive great uncle to Kion and Kiara. And Bunga is Simba’s cousin/brother since he’s the adopted nephew of Timon and Pumbaa plus they have a brotherly bond. Which also makes Bunga kind of like an uncle of Kion and Kiara too XDD
