Amby & Dexter: The Way of Silent was a small series of animated interstitials on Nickelodeon created by Paul Fierlinger and his wife Sandra Schuette. The title is a play on the word "ambidextrous", meaning "the ability to use both hands", as the characters evolve from a pair of hands.
Amby and Dexter, after transforming into inch-tall people, solve problems together. They do not speak while doing it. At the end, they transform back into the original pair of hands.
