Having a mob drop nothing feels… weird. To me at least. They should drop a rod item like their sibling; Breeze Rods. When placed in a dispenser, when activated; will push all entities (and dropped items!) in a direction by a varying amount depending on that entities “weight” IE a zombie won’t get pushed as far as a spider. If you craft them into Breeze Powder, you can combine that with a snowball to make a breeze charge like their attacks, which, when fired from a dispenser functions identically to their attack
