Red Worker Ants will commonly lay eggs in the area when the population is low, in which they can be looted by the player or left to hatch. The egg rooms are easily noticed by the ruptured eggs located on the floor of the room. The cave also has multiple rooms, such as the egg rooms, main chambers, and the treasure rooms. The anthill is fairly large, holding multiple rooms and corridors dimly lit up with Slime Mold Stalks.
The cave can be navigated easily with a full set of Red Ant Armor as long as the player does not attack a ant or pick up an egg. The area also counts as a Explorer Quest area, having a flag near the entrance when the quest is accepted. It is the only place that the player can obtain Red Ant Eggs as of now, as well as holding Rotten Bee Armor. The Red Anthill is currently the 2nd largest Anthill in Grounded, located near the border with the Central Grasslands and the Haze. The area also holds the Black Anthill Lab, being found throughout the entire area in two sectors. About 5 of these rocks are found in the biome. Along with this, many rocks are found blocking key areas of the biome that require a Bratburst to break. Along with this, the soldier ants in the area are fairly cramped into certain areas, with two areas being a hotspot for large clusters of them. The actual cave is somewhat lit up and full of lab wreckage. The Trash Heap one requires a Gas Mask to reach while the Sandbox one can only be reached via the zipline in the Picnic Table or by building inside the Sandbox. The Black Anthill has two entrances, both relatively difficult to get to. It is also one of the best places to gather Style Nuggets and Tough Nuggets. Due to its large size and dangerous creatures, the developers have compared the area to a large dungeon. The Black Anthill is the largest anthill in Grounded, found the south-western most location of the Backyard, with entrances located in the Trash Heap and Sandbox.
