New agressive mob - Blizz (Ice Caves/Ice Chambers)

I was thinking of a new aggressive mob named Blizz 

It could look similar to Blaze and Breeze, and because the upcoming update is about Ice Caves this is a good occasion to add it

Let's say that Blaze is a Fire Elemental creature, and Breeze is an Air Elemental creature

Blizz would be a Water Elemental creature. It would be stronger than Breeze, but weaker than Blaze

Blizz would throw water projectiles at the player that would fill small areas with water, making close combat a little more challenging because the water slows the player down, unless the player is prepared by possessing sponges or a ranged weapon or splash potions with negative effects in the inventory. It could sometimes throw Ice Balls at the player to inflict damage

After receiving too much damage from the player, Blizz would temporarily form an ice shield around its body, so that the player must break it before killing the mob

After dying, Blizz would drop Ice Balls and Water Balls

Water Balls are a new ranged weapon, very effective against Blazes, Magma Cubes, Endermen, Endermites, Snow Golems, and Striders. Ineffective against Drowned, Frostbite, Stray, Dolphin, Salmon, Cod, Frog, Squid, Glow Squid, Nautilus, Zombie Nautilus, Elder Guardian, and Guardian

Water Balls can also be used for drowning other mobs or covering the holes with water, but it'd take a lot of them to fill the area properly.

I came up with the name Blizz, thinking of a blizzard. But I wouldn't mind if the developers decided to name it differently
