Beetle Vs... Beetle? (edited)

As the Beetle foamed at the mouth, the hill trembled once more. This time, it seemed to shift a bit as something began to burrow out of it.

A glossy horn, as black as the Beetle's carapace, poked out from the hill. In comparison, both of their horns were roughly the same size, albeit the one coming out of the hill was just a tad bit longer.

The surface of the hill then continued to expand before exposing a human-like face just like the Beetle's.

The difference was that it was covered in thin, narrow roots that infested it like throbbing veins.

The place where its eyes would be was replaced with thick branches with limp roots at the end.

Its teeth were jagged and decayed, supposedly over a long period of time.

And lastly...

Lillian stared at what seemed to be another beetle exiting the tall dirt mound with a shocked expression.
