I was in the menus and I saw the splash saying "Oh, ok, Pigmen!". Since zombie pigmen are replaced, change it to "Oh, ok, Piglins!". You can add the old splash to the old texture pack. And also why not retexture the piglins to pigmen in the old texture pack? You did it to the crying obsidian in java (that was a suggestion tho, but please change the splash.)
