Splatoon is a video game created and published by Nintendo and it was just released. It's a game about covering as much turf as possible by spraying the ground using special ink spraying guns and what makes it most unique is you can change into a squid form and ride inside the ink allowing you to go much faster and giving it a stealth edge.
As far as I can tell there are no barefoot options in the game but that doesn't mean there isn't official art and a rather well hidden, unfortunately not the best resolution art with a barefoot model!
So far this is the only Inkling stuff that I am aware of but I did do some research before this post. There may be some stuff later with post-content and I will gladly make more posts if such content gets produced.
I'll be doing a "Is it Wrong to Pick up Girls at a Dungeon" post tomorrow! There's 3 episodes worth of content so it's going to be a big one! Certainly not as small as this haha.
If you know of any official content then I'll be glad to update this post! And as always, thanks for reading!
