Hide and Seek with Rascal

I propose to add new levels to the game in the form of caves. The player could freely explore them and could find lush caves, dripstone caves and deep dark caves with ancient cities (which I will cover in another post). While exploring, the player could find chests with new items (which I will discuss in another post), spawners, new spider caves with a new boss, a spider queen (which I will discuss in another post) and a new passive mob which would be Rascal known from minecraft 1.20 voting. finding it, the rascal would run away, and spawn elsewhere in the caves. After finding it three times, rascal would drop an item that has a high chance of being unique.
