Consolation Award: June Foray won her only competitive Emmy for appearing on this show. She was a guest star. On one episode. And she'd never even been nominated before then - keep in mind that for most of her life the Emmys didn't even have a voice-acting category. So many people are seeing the Garfield win as a consolation prize for her entire legendary career.note The next year, she won an honorary award.
Frank Welker voices the majority of the extras and secondary characters. In fact, if there's any minor character with a speaking role you can expect them to be voiced by Frank 90% of the time.
In one episode, Garfield is terrorized in a nightmare by a talking scale (also voiced by Frank Welker); over the course of the dream, the scale slowly changes its shrill voice until it winds up with Frank Welker's Dr. Claw/Soundwave voice.
