The Giant Hole Biome

I was playing a dropper mini game and thought it would be cool to have a biome full of holes, some with dropper minigames and some that are just prank holes. It would be found in the overworld and the parts you have to dodge are a corresponding block. (so you can't cheat). And it could have other structures in the biome (Villages, Dessert Temples, etc.) You could change the ground to any block in the biome (Maybe make it blend in with others by putting a desert by a Giant Hole Biome with sand as the ground.
