I want to use the /execute command and replace a snowball with a creeper, using this command:
/summon Creeper {Fuse:1,ActiveEffects:[{Id:14,Amplifier:11,Duration:10000,ShowParticles:0b},{Id:7,Amplifier:"0",Duration:10000,ShowParticles:1b}],Attributes:[{Name:generic.maxHealth,Base:2}],Silent:0,Riding:{id:"FallingSand",Riding:{Fuse:1,id:"Creeper",ActiveEffects:[{Id:7,Amplifier:"0",Duration:10000,ShowParticles:0b},{Id:14,Amplifier:"0",Duration:10000,ShowParticles:0b}],Attributes:[{Name:generic.maxHealth,Base:10}],Riding:{id:"FallingSand",Riding:{Fuse:1,id:"Creeper",Attributes:[{Name:generic.maxHealth,Base:10}],ActiveEffects:[{Id:7,Amplifier:"0",Duration:100000,ShowParticles:0b},{Id:14,Amplifier:"0",Duration:10000,ShowParticles:0b}],Riding:{id:"FallingSand",Riding:{Attributes:[{Name:generic.maxHealth,Base:10}],id:"Creeper",Fuse:1,ActiveEffects:[{Id:7,Amplifier:"0",Duration:100000,ShowParticles:0b},{Id:14,Amplifier:"0",Duration:100000,ShowParticles:0b}],Riding:{id:"FallingSand",Riding:{ActiveEffects:[{Id:7,Amplifier:"0",Duration:10000,ShowParticles:0b},{Id:14,Amplifier:"0",Duration:10000,ShowParticles:0b}],id:"Creeper",Attributes:[{Name:generic.maxHealth,Base:10}],Fuse:1,Riding:{id:"FallingSand"}}}}}}}}}}
However, it's not working. It only spawns one creeper with no custom effects. What's wrong?
