You can find the string "Pancake Mountain" in zc_list_data.cpp
What is a pancake mountain?
That's the term used in the editor dropdown for the Gameboy style mountain auto combo layout. It's used for automating mountain placement in tilesets that use those kind of mountains. Feel free to blame me for the name.
