Seiya - Cave Along

But  when  the  floorboard  to  the  old  house  finally  comes  into view, Seiya suddenly stops and places his left hand on the dirt wall.

“Hmm? What are you doing?”

A massive cavern thereupon appears behind the wall without even making a sound! I stand back in shock, but Seiya steps inside.

“S-Seiya?! Wait!”

I shortly follow after him. Seiya illuminates the cavern using a glowstone from the item pouch. It’s a very mysterious enclosure. Although the narrow cavity can  hardly  fit  us,  a  new  cavern  forms  whenever  Seiya  approaches  a  wall. Moreover, whenever we continue down a new path, the way we came closes off and disappears. It feels more like the space is moving for us, rather than us digging holes and moving the dirt ourselves.

“This is amazing! Is this earth magic?”

In a lowered voice, Seiya explains:

“Cave Along. It’s essentially a mobile cavern that allows you to freely walkthrough soil.”

He then slows down his pace.

“We’re currently around one meter underground outside the shack.”
