thats probably it, with yukkuris being mute i personally feel that they are actually animals, instead of magical creatures. and that makes them seem much cuter to me.
Hmm, tehcnically they aren't mute, it's just the author not making any dialogue. It's like this guy's works are some sort of mute movies, rarely having any dialogue of any kind, even for the anons.
In b4 piano music to give bgm to this "Mute" Movie.
