They accidentally uploaded a video early on youtube. I got a link to a lq version of it from an anonymous tumblr user.
For me the most interesting thing in the test video was a shot of a little green guy that was turned away from the camera, with a white plate on top of it’s head, a turtle shell on its back and a tiny tail. It’s a fucking Kappa.
Kappa’s if you don’t know, are Japanese yokai (demons basically) with humanoid and amphibious characteristics that inhabit rivers and ponds. They have cavities on top of their heads that are literally called “sara” meaning a plate or a dish. The sara is supposed to be filled with liquid that gives the Kappa its powers and keeps them alive when they’re on land.
Furthermore Kappas have many different names (one source is telling me there are up to 80) and one of the more common ones is kawaso, meaning otter.
