Knothole

Knothole is a village of the Kingdom of Izumo hidden deep within the Wood Zone on Westside Island during Dr. Eggman's foundation of the Galactic Eggman Empire. It was the refuge of Sonic the Hedgehog and his friends, Tails, Knuckles, Amy Rose, Team Chaotix, Vanilla, Cream and Cheese.

Early Times
When Eggman invaded Konohatropolis, the kids of the city, including Sally, Antoine and a serverly injured Bunnie were rescued by Rosie and Chuck and taken here. Rotor came later, wanting to come in Konohatropolis, the "greatest city in the world", but only finding the city invaded by Dr. Eggman's forces. The village became the children main base of operation when, inspired by Sonic's heroism, Sally formed the Freedom Fighters. Eggman however had still managed to create a powerful empire for himself and was able to use it to spread his evil ambitions across the globe but would continually come into conflict with his mortal adversary Sonic the Hedgehog and the Freedom Fighters each time. However Dr. Eggman is able to defeat and destroy the Freedom Fighters by creating EZ-021 Death Saurer and used the Charge Particle Gun.

Invasion of Knothole
While the Knothole Freedom Fighters and Chaotix spent their time relaxing at Freedom HQ, the Egg Fleet began its aerial invasion of the Knothole Village. Paul Prozen Gunther arrived at Freedom HQ and attacked the Freedom Fighters and caused the Team Chaotix to retreat with Vanilla, Cream and Cheese. After capturing all but Sonic, Knuckles, Tails, Amy Rose and NICOLE, Paul Prozen's Berserk retreated. Sonic, the only one of the un-captured citizens who was not buried under the rubble of the former Freedom HQ, ran to Castle Acorn to warn the king of the attack. As he ran through Knothole he witnessed the large-scale destruction. Just as he arrived at the castle, the large structure was conquered. Emerging from the flames was Dr. Eggman in his Death Saurer. Sonic fought bravely against Eggman, but was ultimately no match for the Death Saurer and Eggman destroyed Sonic, Knuckles, Tails, Amy Rose, Sally and NICOLE causing the destruction of the Freedom Fighters and Egg Fleet returned to Konoha Canyon.
