Drowned model/textures

I've remodeled the drowned into a aqua droid . the problem I'm having is I've made the model and textures I've blanked out the texture for the drowned , drowned_outer_layer , husk , zombie & the zombie_villager but the game is still pulling a head file/shape and putting it in game . I was able to get rid of everything else. There must be another file connected to the drowned but for the life of me i can't find it.

Any help or suggestions would be great and very appreciated.
