The Adolescent Biohazard Bedouin Amphibians (often shortened to ABBA {not to be confused with the famous Swedish music band} or Bedouin Amphibians) are three fictional adolescent anthropomorphic toads named after Ancient Greek philosophers. They were trained and/or raised by their anthropomorphic monkey-like sheik. From their home base in the sewers of Chicago, Illinois, they battle petty criminals, sinister overlords, mutated monsters and alien invaders while attempting to remain hidden from society.
