Try to defeat The Flying Pig whilst your inventory never stays the same...
~Setup and Starting~
When you install this datapack to your world type /reload (with cheats enabled) and you will be given one minute to gather as many items as you can before your inventory begins to change.
~The Bossfight~
To complete this challenge you must murder any poor innocent creature with a porkchop (it just needs to be the last hit) and you will be shot up into the Flying Pig's arena. To end that pig's career you will need to punch his fire-chops back at him (you need to hit him 3-4 times before you will be victorious). However this is not as easy as it sounds... He will drop explosive pork chops that will shred you if you are not running away. Even if you have good armor.
Enjoy!
