A type of unnamed monster from the original
Muppet Show. They were initially in many of the sketches as main chararacters, but as the seasons progressed, and the number of named muppets grew, they
eventually were only seen in supporting roles. There were many "frackles" made, but the
green and blue frackle muppets were used most often.
"Although
originally made with three pointy fangs,
the green frackle only had two in later seasons."
"The blue frackle has a cameo in this episode of Pigs
In Space!"
