Nice! I worked on this same clip for my post production class at Berklee. It's definitely difficult from a sound design perspective, with all the animated frantic movements and everything. And the damn baby sounds. Take a look at the video on my page, it's in english.
I would love to be Jack-Jack for all the special powers, but I would be more of a problem for the folks at home than Franklin Richards. Anyways, is it wrong to feel jealous?
@BieniAlala: this is not Japanese, it's Cantonese Anyway, this is a terrible upload not because it's a Cantonese version, but the one who uploaded it didn't add anything on the title to label it and tell others what language this version is. Imagine everyone expect to hear something in English and turns out to hear some language never heard before. PS: I understand Cantonese and I have to say this Cantonese version's voice actors and the translation are horrible, make it not funny at all.
