The Swamp Critters
Titular band from the PBS kids' television series The Swamp Critters of Lost Lagoon (1995-2000).
The show was created and written by real 1960s singer Bobby Goldsboro, that archon of average and maven of mediocrity.
The characters were played by actors in suits, but the mouth and facial movements were done with animatronics.
Lineup: Big Al Gator, Billy Bob Possum, Gumbo Fiddler Crab, Ribbit E. Lee, Ima Dilla, and Joe Raccoon.
