New mobs,updates and items

Hello there Minecraft,I thought of some new stuff that you could add to Minecraft,how about some new biomes,first ,do you ever think that the rocky shores are kind of plain,we’ll say no more, these are geysers, they can blow you up with in 20 blocks high.Next,in the nether,we have crimson and warped forests,well why don,t we have dead warped forests,these forests spawn near lava falls and with zombie pigmens and zogins.I also thought of three more mobs that you could add to the game,first we have the snail,the snail can spawn in swamps or plains,it can provide snail slime,which can be used to make snail blocks,it can players stick on it to cross over giant holes.Next, we have the totem companion, you can make it by using a new item called living dust, you can find it in desert temples, or in woodland mansions, combine it with a totem of undying, and you can get it. Finally, we have the giant clam, this is Mob can be found in coral reefs, you can use a shovel to get it, and you can place it any time or anywhere you just need to places in water and a new update, there is a rare present chance that wandering traders can have a full ore trading session.
