The people, once Sasuke and Hashirama find the main road and then come into view of the village proper, don't look much like humans. Some of them distantly resemble some of the odder clans, but not very. There's a girl with a humanoid upper half (except for the faint shimmer of scales on her flesh) that fades into a tail with no legs, using a wheelchair to push herself around. There's an older girl, a bit larger than Sasuke or Hashirama but still looking juvenile, floating behind an empty wheelchair she's pushing as she talks to her maybe-sister. Both have blue-green hair that shimmers with flecks of trapped stars, and both wear clothing woven from seaweed and heavily decorated with coral beads.
There's multiple beings that seem to resemble different types of crabs, many of them capable of holding themselves slightly upright to carry things. Most of them wear decoration, but there's not really clothing.
There's a crowd of octopuses, most of them half Sasuke's height, mostly colored in dull shades of blue and brown, pulling themselves along the ocean floor. Some of the larger ones seem capable of hopping and floating short distances.
There's assorted variations on humanoid jellyfish, who seem to have an easier time flying than most of the village's inhabitants.
Many of them turn to look at Sasuke and Hashirama when they round the corner, and one jellyfish girl flutters her bowl-hair and skirt and flows over to them, making curious chirping noises.
