If you were asking "But madcowchef, what if I need a really big cavern to house my tarrasque?" here is the answer. A sample of the majority of pieces I did for a big cave construction kit. The scale leads to less detail, and as I envisioned my map tiles being good for quick setup putting together a big cave is somewhat guaranteed to take a few tiles at least so isn't at the core of how I pictured people using them. None the less I included them for the sake of completeness and including a big cave at the end of some little tunnels seems appropriate.
