I thought this was one of the best episodes. It's mostly because of how cheerful it is. I really love that Easter egg where the fish soul comes out. Do I think animals go to Heaven? Yes, I do. I admit that I don't understand any of that stuff, but I believe it.
I don't want to get into a religious debate here. May I ask questions? No, this series has long ended. Most series here have. The animation isn't bad.
