Update "Losed Features"

Hello! I would like to suggest adding mobs and biome improvements to the game that lost in official votes (I also take into account the llama or alpaca vote), just in case I will list them in chronological order:
Alpaca (Jeb's Twitter post)
Barnacle (2017 mob vote)
Great Hunger (2017 mob vote)
Wildfire (2017 mob vote)
Moobloom (2020 mob vote)
Iceologer (2020 mob vote)
Glare (2021 mob vote)
Copper Golem (2021 mob vote) (you can add his old ability to press random buttons in some interesting way)
Rascal (2022 mob vote)
Tuff Golem (2022 mob vote)
Crab (2023 mob vote)
Penguin (2023 mob vote)
(I broke the order here, it was 2018)
River Dolphin (pink dolphin from Chinese mob vote)
Golden Monkey (Chinese Mob Vote)
Chinese Deer (Chinese Mob Vote)
Crocodile (Chinese Mob Vote)
Zach (Minecraft Cat Contest)
Coco (Minecraft Cat Contest)
Eliza (Minecraft Cat Contest) (Not finalist, but famous)

Biomes:
Savanna Update (2018 Biome Vote)
Desert Update (2018 Biome Vote)
Swamp Update (2019 Biome Vote) (maybe already fully added, I don't know for sure)
Badlands Update (2019 Biome Vote)

(You can see what all this had in common in the pre-vote videos, or think of something, or come up with something from scratch, for example, the alpaca's abilities)
(You can also add features of winners, what didnt was released)
(Mojang dont need to add all cats from Minecraft Cat Contest,
it will be too much, those that I wrote will be enough I think)
