Weird rubber duck faces are kind of a rubber duck thing, and the mega duck seems like a pile of various sized ducks.
Considering the bath has a TV screen, I assume it is something electronic but it is too blurry to see. You can have sockets for shaving gear or something more specific. It all looks very Japanese.
Under water hair splays out and floats/waves in the water as pictured, out of water it is slick.
Nothing really leaps out in these pictures to me that says “that’s impossible” rather than just unclear due to angle and picture quality. If anything the degree of consistency between each of the separate images gives me more cause to think it is real.
