Sandy Cheeks is an anthropomorphic brown squirrel from Texas with soft brown fur, tan cheeks, a light brown belly, small rounded ears, a pink nose, large close-set eyes with black pupils and occasional eyelashes, a prominent white buck tooth, four-fingered hands, three-toed feet, and a long bushy tail. In the reference style she has an extremely curvaceous, athletic build with large breasts, a narrow waist, wide hips, thick thighs, and a prominent rear. She typically wears a purple strapless bikini top and matching tutu-style skirt over a light green bikini bottom, though other looks include a tight revealing pink cut-out outfit with her space helmet or a partially unzipped white spacesuit over a star-patterned bikini. A proud, competitive cowgirl, she speaks with a heavy Southern accent full of slang like “Howdy,” “Y’all,” and “ain’t,” often using colorful similes. Highly intelligent, physically fit, and athletic, she remains one of the more caring and level-headed characters despite her strong pride. Lives in a dome with a tree in the middle.

Pearl is a tall, 18-year-old anthropomorphic gray whale girl with an extremely exaggerated, ultra-curvy figure—enormous heavy breasts, a soft rounded belly, wide hips, thick thighs, and a huge round rear. She has smooth gray skin, blonde hair in a high ponytail with a pink scrunchie, a long rectangular snout marked by a red heart that becomes lips when she kisses, solid blue oval eyes with purple eyeshadow and six eyelashes each, plus five ventral neck pleats. Her main outfit is a pink cheerleader shirt with a dark magenta skirt featuring the letter “P,” paired with white go-go boots, while she remains a cheerful, naive, high-spirited mall-loving teen who just wants to fit in.

Ms. Puff is a heavily anthropomorphic, extremely obese pufferfish woman with pale beige skin, brown freckles, short blonde hair, large green eyes with age wrinkles, and a small pink-lipsticked beak. Her body is massively soft and voluptuous, featuring an enormous heavy bust with large areolae, a thick belly, wide hips, and teal fin-limbs. She wears her classic blue sailor’s outfit with a yellow string necktie, blue sailor cap, red skirt, and bright crimson shoes, often strained or partially open over her exaggerated curves, with a smug or seductive expression.

Karen is a sophisticated female computer/robot with a light-blue CRT monitor for a head and a curvaceous gray metallic body featuring segmented plating, large breasts, a narrow waist, wide hips, and thick thighs. Her black screen usually shows a yellow heartbeat line but displays stylized digital faces (especially smiling ones when happy), pictures, characters, TV footage, or security-camera feeds; she wears a pearl necklace and in a red dress or white lab coat. Sometimes a red bikini when spicy. She speaks with a heavy Midwestern accent and is intelligent and sarcastic.
