Whips & more mod/Oreo Crawler

The Oreo Crawler is a Post-Moon Lord enemy that spawns after Corite Knight has been defeated.

It behaves exactly like the Giant Tortoise, crawling on the ground, and sometimes rolling into a ball and charging at the player.

It drops Oreo Cookie Ore and Oreo Cream Ore which is a material for endgame items.

Spawn
It spawns at night, though pretty rarely.

Having a Blood Moon active, a Water Candle nearby, and using a Zerg Potion can dramatically increase the spawn rate, allowing you to get the ores much quicker.
