I would spawn 1000 white sheep called noobcrew from the top of the end & watch them fall to their death's. Rinse and repeat.
Give myself too much money and use this command on a command block: /summon Fireball ~ ~3 ~ {ExplosionPower:50,direction:[1.0,0.0,0.0]} And this /summon PrimedTnt ~ ~1 ~ {Fuse:120,Riding:{id:"Sheep",CustomName:"Noobcrew"}}
