Ender Grotto

This biome is a biome which has:(you guessed it)endermen, shulkers and more blocks!
Legend has it that there was a small tribe of endermen which preferred living in caves. These endermen were from The End, but they were laughed by other endermen. They were squeezed out by other endermen and came into the Overworld. They evolved into endermen that will only leave the grotto if someone disturbed them. For the shulkers, some of them followed those endermen into the Overworld. The biome includes the original end stone(some) and a type of corrupted end stone(inverted end stone color), and some end grass(inverted grass). There is a structure called End Base protected by hostile endermen. There will be many traps like lava, fireworks or dragon fireballs.
