I knew there was going to be a song called "Duties of the King" and that Zazu and Simba would sing. I hadn't listened to it to avoid spoilers, but I thought it was going to be meant for Kiara xD It was a nice surprise to see a subplot going on with Simba, Nala and Zazu, who hadn't appeared together in a song since "I Just Can't Wait to be King", it felt somewhat nostalgic
(I still can't get used to Rob Lowe's voice as Simba, though ><).
The funeral scene was very touching, especially knowing now that this elephant (I think he was named Amanifu) played an important role in getting the Pridelands back to normal, that's good canonical information there. Also, I didn't expect we would see his body, especially in a Disney Jr. show, but it's good to show kids that death is a natural event in the circle of life. It was nicely played, even with the awkward poop joke (it's perfectly ok to have a bit of a laugh at a funeral, sometimes)
The main story was also pretty good, I kinda thought it would be about Kiara finding out how hard it is to be Queen and making a bit of a mess, but besides the meeting alone with Janja, I think she handled it pretty well. The sibling rivalry scenes were funny too.
Oh and this line:
"Six on six >:3 ... Forget it!! D:" That was priceless
