The Kaboom Moon mod adds a new moon to Enhanced Celestials, increasing spawns of creepers.
During the rare Kaboom Moon event, the weight of creeper spawns will be greatly increased, and during a Super Kaboom Moon, all mob spawns will increase as well, leading to a world overrun by walking explosives.
I have no idea why you'd want this, but here you go.
