*Mindy is an anthropomorphic fox with pale yellow fur, orange hair in a style of high ponytail by a gold hair band with green details, teal eyes, pointy ears, a brown nose, and an orange tail with pale yellow on the tip. She usually possesses pale pink eyeshadow. For attire, Mindy wears a fuchsia and purple robe with yellow polka-dots that is fastened with a gold buckle, purple leggings with yellow polka-dots, and purple boots with few small yellow polka-dots. After being forced to leave her home with her father, Mindy now wears a grey-blue short-sleeved jacket, a blue scarf, denim pants, and brown boots.

Sonia is an anthropomorphic hedgehog with a slim, curvy figure, bright fuchsia fur, pink hair in a style of straight spikes and full fringes, peach skin, and black eyes like her siblings.

For attire, Sonia wears a dark red, sleeveless top, a dark purple miniskirt, and a gold belt that forms a pointed shape at the front and bottom with a round, blue gem in the center of the belt. Unlike most Sonic characters who wear white cartoon-style gloves, Sonia wears long, purple ones that go halfway past her elbows. Sonia also wears red pants under her skirt with dark purple spots on the knees and a thin, purple stripe on each of her thighs, a pair of dark purple boots with red toes, and her royal medallion around her neck. In Flying Fortress, when visiting a beach, Sonia wears green sunglasses and a blue bikini with yellow stripes. In The Big Melt, she goes to the beach again and instead wears a yellow, midriff-baring t-shirt with a white stripe across the chest and a yellow bikini bottom. Sonia also has two known winter outfits, identical in appearance but with differing colors.*
