The Cave's Voice is a very creepy voice of the very creepy "Cave" and the main neutral antagonist of the 1991 cartoon film The Little Engine That Could. He was a cave resembling a demonic face with claws, teeth, two eyes, a nose, and is only heard saying "Too little. Too little.", before starting to drop icicles and collapsing in an avalanche as Tillie narrowly escapes.
He was voiced by Peter Cullen.
