I think something like this could be really cool as a skin for the Drowned. The trident would get a completely new meaning with this.
Sadly there are some problems with the Zombie model in skin in PMCskin3D, so I used the Zombie Villager ... which turned out to be an improvement, because I could make use of a combination of the the head and the helmet and the brim layers in order to make the trident stand out even more.
