Not sure if it's worth putting into the video, but I wanted to share it anyway. Donald's Atlantica form is the same as Ursula's body because they both specialize in magic. Which was a really cool detail I realized after a couple of playthroughs in the first and second game.

Happy Birthday!

Happy birthday Alex!! 🎉 Keep up the amazing work!

Congratulations, you two. I hope you guys have a happy life together!

Happy birthday!! 🎉

This is the first time they had Loona confirm herself that she's on orphan, so that's a possibility. But they can still throw us a curveball by revealing that they're alive but had to give her up for one reason or another.
Hopefully, that reason is something akin to Leela's backstory from Futurama.

Oh God, that's horrible, I'm so sorry that happened to you.
