Lung is bright, peppy, and gets along with just about anyone. He works as a mail clerk and lives with his long-time girlfriend Brush.

Lung doesn't give much thought to plans for the future, and they don't really have the dedication to dwell on the past. He's happy living day-to-day, and can adapt easily to meet any challenges that arise.

He doesn't have a lot of patience for grooming his somwhat long fur, so he can be prone to getting mats.

His voice is somewhere between Michael J. Fox (Milo Thatch) and Shannon McKain (Graham Burns)
