Mutant Mobs

Every mob should have a mutant version, but they don't spawn this way. You have to use the chemical x potion and it works on yourself because you grow so tall and so buff. And you can one shot the warden. You can make this on a brewing stand with a diamond. And chemical x lasts for ever on you! And the effects are jump boost, flight, speed and strength. Also, when you kill the mutant mobs, you get a custom weapon of theirs.
