Big enough for Ssarak to stand but hardly any room to jump. Rough dimension: ten-foot high ceiling, 60x35 feet, however there's a specific internal structure that I won't reveal until you actually go inside. I'll tell you this much: There are "Rooms" inside. To compare the cave is roughly the size of a small house, but underground. use this as a reference.

If you can see it on the image, there is a square grid. Each square is roughly five-feet by five-feet. The cave itself would be what the house in the image is, but without a rear entrance.
