Minecraft: Polar update (credit to Nekoma for some ideas)

This post involves lots of frost and ice related ideas including 3 new mobs, a brand new grand structure and biome, and plenty more features, items and blocks!

Note: This post includes some ideas from the Youtuber Nekoma and I will say so if, but the real star of the update is completely my idea.

Ice Shards

If you break ice or icicles without silk, you obtain 4-6 shards. You can craft ice with 9 or use it in armor trims.

Iceologer

The iceologer previously lost the 2020 mob vote, and now it is returning to the game just like the copper golem! The icologer spawns in igloos or in raids in a snowy village. It can freeze you by dropping icicles on you with it's magic and throw ice cubes at you. It turns into an ice bat when it drops to a certain HP and will keep flying around until you hit it and it returns to it's normal state. Upon defeat it drops compacted ice, which freezes nearby water and turns lava into obsidian. Watch Nekoma's mob vote videos for further details.

Frozen Cavern

This biome can only generate under other cold biomes. The whole cave is made of ice, with icicles (looks like pointed dripstone) and ice clusters (looks like amethyst buds) cover this pretty cave. The deeper you go the ice gets denser, with ice higher and blue near bedrock. You can also find ores and other things inside the ice, so if you can get ores without a pick. This was Nekoma's Idea.

I don't have enough room for my last idea so look for the idea titled Minecraft: Polar Update 2 Frozen citadel.
