Lady Walrus is essentially a doppelganger of her Sonic Boom World counterpart. As such, she is an anthropomorphic and somewhat chubby walrus, almost a head taller than Sticks. She has violet fur with a single hair curl on her forehead and a large bust. She also has peach skin on her wide muzzle and around her eyes, small tusks, a black snout and purple eyes. For attire, she wears a vibrantly-colored blue dress with a green waist string with pearls, white cuff-less gloves, light blue high-heeled shoes, a necklace with white and pink jewels resembling pearls, a gold bracelet, a small white hair bun cover, and purple eye shadow.
Lady Walrus eventually visited the Village Center with her son. There, she backed off when her tyrannical ruler, Lord Eggman, arrived. She was then left astonished when she saw Sonic the Hedgehog taunt Eggman.
Lady Walrus is a protective mother who would stand in-between her son and Lord Eggman to protect the former. She also greatly fears Lord Eggman, and the very notion of someone standing up to him is quite shocking to her.
