Georgette Walrus

Georgette Walrus is the mother of Rotor and Skeeter Walrus and the wife of Sherman Walrus. She currently lives in the subterranean city of Iceborough in the Northern Tundra. Twice has she and Skeeter been brainwashed by Dr. Robotnik and was permanently freed the last time.

Brainwashing
Years after Rotor left the Walrus Herd to visit Mobotropolis, she and the herd lived peacefully until Robotnik detonated a neuron bomb over the region allowing him to brainwash the herd into serving him. They were to be used in a scheme to freeze the entire planet, but the efforts of Rotor and two members of the Arctic Freedom Fighters set them adrift on an iceberg. Later, the effects of the Ultimate Annihilator freed the Herd from this control, allowing them to live peacefully for some time. However, Dr. Eggman soon made his first foray into the region, placing the Herd under his control and driving Rotor, who had returned to spend time with his family, out of the region. Fortunately, the Arctic Freedom Fighters were able to get him to safety, though the Herd remained in Eggman's hold for the time being.

Found
The Knothole Freedom Fighters eventually returned to the region, using the magical Sword of Acorns to free the Walrus herd from Eggman's grip once again. Following this, they entered a period of peace, and their city of Iceborough became a prominent area of the region.

Dark Egg Legion
The Arctic Freedom Fighters later contacted New Mobotropolis to inform them that a chapter of the Dark Egg Legion had captured the Walrus Herd. Sonic the Hedgehog was dispatched to aid the team in freeing them, and learned from them that the Legion had constructed a Psionic Emitter to aid them in using their sonar abilities to once again brainwash the Walrus Herd. The enslaved Walruses were employed in maintaining the Legion's new base above water, and a horde of them armed with spears, axes, maces, and swords stood guard as the Freedom Fighters arrived to liberate them. Sonic was fighting them until he was hit in the back by Georgette and Skeeter. Not wanting to hurt them, he tried to talk some sense in to them, but Erma had to interfere to keep him from getting clubbed. Eventually, Rotor and Silver the Hedgehog arrived at the vicinity and broke into the base. Silver then used his Telekinesis to perminenly free Georgette, Skeeter, and the rest of the herd from the legion's control, as well as forcing the legion to retreat. On the way to Iceborough, Georgette repeatedly explained to Silver that Boomer was actually Rotor's childhood nickname. She later complimented Rotor on being a Freedom Fighter at heart and helping to run Mobotropolis. She also says that his father would have been proud of him.
