The Houndcats were five crack agents--leader Stutz, strongman Muscle Mutt, master of disguise Puddy Puss, electronics whiz Rhubarb and daredevil Dingdong--who received instructions of their latest mission via exploding tape-recordings and used their specialties to foil evil. If this sounds a bit like "Mission: Impossible", it's no coincidence. Sparkplug was the name of their car which took them to their assignments.
