Tissou's Zombie Pack, is an addon for minecraft modifying only zombie, husk, villager zombie, and drowned. This one will also modify the sounds of the mobs indicated above.
This resource gives the game an almost infinite diversity. Because this resource pack brings to the game more than 1000 different textures.
I challenge you to find two identical at the same time.
Keep in mind that this texture pack requires Optifine, because to be able to have diversity as well as shiny eyes, it will be necessary.
