Knothole is a location that appears in the Sonic the Hedgehog television series. It is a hidden settlement within the heart of the Great Forest on Mobius, which serve as both the home and base of operations for the Freedom Fighters, a small band (led by Sonic the Hedgehog and Princess Sally) dedicated to overthrowing the evil Dr. Robotnik.
Knothole is an above-ground village built into harmony with nature. The heart of the village is the living quarters, small thatched-roof huts where the Freedom Fighters live. The village is accessible only through hidden entrances at various points in the forest.
Originally, Knothole was a hidden retreat for the royal family, who otherwise lived in the capital city of Mobotropolis. When Dr. Robotnik took over and banished the King, he began to round up the citizens of Mobotropolis to be roboticized. Sonic, Sally, and their friends were taken to Knothole by their caretaker, Rosie. Eventually, the group would become the Freedom Fighters and would use Knothole as both their home and center of operations. Mobotropolis, under the control of Dr. Robotnik, was renamed "Robotropolis" and became a polluted, factory-infested wasteland.
- The Sonic Live in Sydney show was (presumably) located at an area in SegaWorld Sydney called "Knothole Village". On top of that, the background for the show looks reminiscent of the design for Knothole in the Sonic the Hedgehog television series.
