Shrink Datapack by Pious


With this Datapack you can shrink yourself and mobs with pistons. To shrink you need to stand under a piston and extend it. To grow you need to stand under a sticky piston and retract it.
  • Stand under a slab which is one block above you and extend the piston to shrink to 0.75 size.
  • Extend the piston to shrink to 0.5x size.
  • Stand under a slab and extend the piston to shrink to 0.25x size.
  • Stand under a cauldron while you are 0.25x size and extend the piston to shrink to 0.01x size.


Have Fun :D

An option to make it so that if you enter water or drink milk it would make you regular size with the advancement: Just add water! would be funny

I fail to see how reverting to your regular size with milk, would not be useful, but fair, I guess.

Sorry, I meant I think it would not fit in the datapack (because at the moment, just pistons are used) , but maybe in the future :)

For .75x you could have the same set up as .25x but one block up.
