The Frostleaf, the Propellers, and the Frozen effect

1.Frostleaf

This is a new mob. It would spawn in the snowy mountain biome, the snowy tundra, ice spikes, and snowy taiga. It would be a small leaf monster that doesn't attack you. It would look like it’s made of taiga leaves, but they have snow on them. The frostleaf would be tame able, like a wolf, but to tame them, you need to use a frostleaf block, or a frozen leaf. When you hit it, it gives you the new frozen effect. When you kill it, it drops a frozen heart, which you can use to make a frozen effect potion.

2. Frostleaf Block

            A frostleaf block is basically the frostleaf, but a block. You can make it by taking a snowball, and any leaf block, and combining them.

3. Frozen effect

This effect happens when you use the potion, hit a frostleaf, or stay in a snowy biome for a really long time. It makes the edges of your screen bluish, and does damage.

4. Propellers

They would be the new redstone block. If placed in water, it would move any block that it is touching, and 4 blocks to the left, right, up, and down, using redstone.

5. frozen leaf

You can make it by putting a frostleaf block in the crafting place.
