Updated icebergs

The unique thing about icebergs are really the polar bears and that is it. So there should be more dangers and mobs. Once you have stood on the same block of ice for 12 seconds it will start cracking and by 16 seconds it will break and you will fall underwater. The same applys to polar bears and penguins I will talk about later on. At the top of the iceberg there will be a new mob called an Ice Pod that shoots out snowballs that give you slowness and knockback. The Ice Pod will have 20 hearts and does 4 damage every hit. If you kill the Ice Pod it will give an item called an Ice Blaster similar to a cannon that shoots its own snowballs and it will have infinite shots with an 8 second cooldown as it cools back down. To make it to the top of the iceberg there will be an icepick that can be crafted with an iron pickaxe and obsidian on each side and if you climb too fast then you will fall down 2 blocks. If you break a block there is a 5% chance for ice bugs to come out which are similar to silverfish. There will also be penguins that will eat fish and squid and swim underwater also along with laying eggs. They will have a 0.5% chance to spawn as dark blue.
