minecraft jeepers creepers update

I have a great idea for the next minecraft game drop. it's called, JEEPERS CREEPERS! basically, it adds a lot of new things to minecraft:

#1: the creeper den! this is a new minecraft structure/biome, it's this HUGE network of tunnels that are crawling with creepers, inside of it, you can find chests of many potentially usefull materials and treasures (including a special item ill introduce later!), tons of creepers, and the jeeper chamber, which is a special room where you can spawn a new boss mob using a block called the jeeper spawner!

#2:  this is something ive been wanting to be added to minecraft, the baby creeper! honestly, i think this would fit perfectly with the tiny takeover update, here's the mechanics:

the baby creeper makes a tiny explosion, only about 5 blocks total in damage, it runs 3x faster than a regular creeper, and it can be tamed with a special item found only in the tunnels of the creeper den, the boomberry!

#3: the jeeper: this is a new boss mob that can be summoned when 4 jeeper spawner blocks placed within a 10x10 block radius are all activated with redstone. it hurls blocks of ancient TNT at you, which creates a much bigger explosion when dentonated (the ones thrown at you dentonate automatically)

#4: ancient TNT: Ive covered most of the ancient tnt mechanics already, except for the crafting recipe, basically, it can be crafted just like regular TNT, except with a boomberry in the middle instead of gunpowder. it's also dropped when a jeeper dies.
