Stop Sniffing Around
Hello, do you hate useless things? Me too!
So I made this datapack/mod that will remove the Sniffer from the game... COMPLETELY!
What else does this datapack do? Good question! It also: 1. Removes Sniffer Egg from suspicious sand Loot Table, making the Sniffer UNOBTAINABLE in survival. 2. Has a function that immediately takes care of any spawned Sniffers (~~no Sniffer is harmed during the process~~) 3. Removes all achievements that are related to the Sniffer and modifies those that only include it partialy (such as Two by two) so that they can be completed.
So... did I convince you that this datapack is what you're looking for?
If not, maybe this before and after will:
