Lovecraft first coined its use as the name for a monster (a vaguely humanoid one, in The Dream-Quest of Unknown Kadath ), but "ghasts" have appeared in many other fantasy stories and games. The player can go inside of a ghast by falling through the top of it or flying (or jumping while attacking) up underneath it.
