Herbie was Jon's pet frog. He first appeared on June 9, 1983, with the following day showing that Garfield had eaten him. He later made a cameo as a ghost haunting Garfield along with many of the other animals he'd eaten in the past on October 30, 1994, 11 years after his debut and subsequent departure.

Short for "Herbert," meaning "glorious warrior." Jon had a pet frog named Herbie once. I had a pair of frogs legs named Herbie shortly afterward.
- Herbie still appeared to be in Garfield's mouth on June 10th as his tongue shot out and caught a fly.
