Sculkballs

I saw in Minecraft Live that one of the loot items in the Deep Dark was the snowball. This, however, does not make sense to the biome. Instead, I recommend making a sculkball. This could be found in the chests and could also be crafted with either snowballs, slimeballs, or magma cream and sculk veins. When thrown, it makes vibrations around itself. It also makes vibrations for 3 seconds after it's thrown. This is a way to somewhat distract the Warden while you try to escape. When you hit the Warden with a sculkball, its ears (Badgeri's words, not mine) grow and are more intent to your every move.
