The bug is that whenever I throw a potion of Invisibility or shoot a invisibility arrow at a Shulker it doesn't completely turn Invisible it just leaves a little white Shulker head floating.
step 1 get a splash potion of Invisibility or the arrow version
step 2 splash the potion or shoot the arrow
step 3 observe the floating little head
Its the shulker golem the one that is little
