coreppr

This mod adds "coreppr"—a Creeper with a copper shell.

While the copper shell is present, it moves slower but has higher armor value and knockback resistance.

When you break its copper shell, it drops some minerals and, like a Slime, "splits" into normal creeper and a lightning bolt that destroys dropped items not picked up immediately and turns creeper into a charged Creeper.

coreppr will summon in underground.

coreppr have a variety too--flureppr.Its shell was a fluid storage tank filled with poison.When it be hited,it can shoot slowness IV,and it can shoot a lot of a lot kinds of poison when die.
