Berry travels deeper and deeper into the cave with only guessing which way is which. She does find a few water resources but she still doesn't have any food and any sign of exit or help isn't anywhere near.
As Berry travels more, she's curious as to why the walls around her are getting greener, perhaps moss? The environment is also moist as if the air contains water droplets.
However.
Berry doesn't feel alone.
She feels that something is stalking her the moment she steps her hooves at these mossy tunnels. She keeps her guard up to prepare for what's to come.
The anxiety grows more and more until unconsciously, Berry walks to a bump and trips. And the first thing she sees is a giant bug resembling a cross between mantis and beetle with glowing orange eyes. The bug roars and charges at her.
Berry screams loudly. She picks herself up and runs and flies away, trying to flee from the giant monstrosity bug that sees her as dinner.
Berry keeps running away, going from one tunnel to a room to another tunnel, another room, a hole, and eventually, dead end. Berry is now trapped , and worse, the giant bug can still fit.
Only equipped with her knife, Berry stands her ground and fends off the bug from eating her, but due to its size Berry has a hard time fighting it. She stabs the leg of that beast but that only results in her getting knocked on the wall and making her lose consciousness.
