Herbie fies by walking on air or in space in almost every story, and in those where he does not walk on air, he flies into the past in a grandfather clock or as a costume superhero as the Fat Fury.
A text story in Herbie #3 described the sound of Herbie "trudging through the sky" as "Plop, plop, plop".
