Shenron saying he only grants three wishes for returning customers confirmed my earlier sentiment that lore doesn't matter in Daima and they just do what's funny in the moment. There would have been easy explanations otherwise (it's only one wish due to the ritual or he doesn't have enough power for two more wishes since Dende is now an infant). So, I'll stop mentioning lore stuff.
As for the actual episode: It was fine.
I'm kinda sad neither Korin nor the turtle are considered 'friends of Goku' - at least that's how the wish was translated for me. As for the actual designs, I would have prefereed to have child designs and not just chibis. I guess the main difference here would be their hair, like Roshi for example having some. And of course their cloths, after all a lot of these characters already have cild designs.
I'd like to know what's up with Gohan. Dende reverted back to an infant and Piccolo is a child now. Gohan should be inbetween them (ignoring their different aging process) - so which is he?
Popo seems interesting, his horns are similar to an Oni, I guess. Up until now I'd have classified him as genie. More story on him would be great.
I would have liked more time with the full cast, but I guess it's adventure time now.
