Idea Minigame: Creeper Wrangler

Orginal name: Goomba Wrangler
What you do:
Players must collect Goombas that wander on the field by drawing a complete circle around them with the stylus, but players have to avoid collecting Bob-Ombs that can destroy half of their already collected Goombas. Brown Goombas are worth one point, while Golden Goombas are worth three points. The player with the most points after the twenty seconds are up is declared the winner.

In minecraft:
You need to kill an creeper for one point, and charged creepers for three points. It will spawn cows that will remove half of your score if you hit them once. The game should last for three minutes. You will spawn with an diamond sword with sharpness X.
