Definition
An anthill is a mound-like structure ๐ built by ants as an entrance to their underground colony. It's like the front door to a bustling city beneath the surface. The hill itself is made of soil, sand, or other materials that the ants excavate. Think of it as a skyscraper's lobby, but for ants. It's not the whole colony, just the visible part. Anthills can vary greatly in size, from small bumps to large, complex structures.
