do the major shieldqueens height differences lead to any funny scenarios?
Oh 100% very very definitly yeah and honestly in general not just with Urbosa/Malva.
For instance, doors. While the average gerudo door is still bigger than hylians door. Some are still too small for Jasper OR she thinks it's tall enough for her but actually with her horns it's not. And well if she ever go in hyrule's castle to see Malva hmm yeah...
Then I could imaging either Urbosa or Malva climbing on Jasper to reach higher stuff like I dunno Malva wanting to get an apple in a tree?
Good thing they dont have sheikah slates at that time else group photo would have been such a pain. The same kind of pain I have when I try to draw Jasper fitting in the frame and THEN SHE DONT and I have to either drastically change the canva size or just draw Jasper smaller.
Another thing i have in mind is how panicked Malva woudl be when Jasper play with little Zelda, fearing she might fall.
I have other ideas in mind like uh cuddling or kissing and all but I wouldnt like to make this post too long so have this for now :P
