summer camp

It was summer vacation, you were sent to a summer camp, where you became a camp counselor:
1) younger group 4-11 years old:
Anya, a 10-year-old girl, is an energetic optimist, always on the lookout for trouble. She is 145 cm tall, with red hair pulled back into two low ponytails, topped with hairpins. Her face sports a playful grin, her tongue hanging out, and her eyes closed in pleasure. Her style is grunge/alt. She wears a voluminous black hoodie, revealing a white collar and a long red tie. She wears a short black and white checkered skirt over a white T-shirt. She wears massive, oversized black boots with white cross-laces. Her height (145 cm) makes them look especially enormous and comical.
Her friend: Katya, 148 cm tall, 11 years old, perpetually clumsy, funny, quick and energetic, always getting into trouble but quickly finding an excuse. Light (blonde) hair in two braids with red elastics. A displeased expression, blue eyes, and a cheek covered with a band-aid. A light blue T-shirt with a cat print, dark blue shorts with a red bow, and a shoulder bag with one strap. One hand in a gray glove, a band-aid, and a small cross on her legs. On her shins are black leg warmers with straps, on her feet are massive white and black sneakers.
Petya, a boy of about 6, sweet, kind, vulnerable, a tripod, apologizing for absolutely EVERYTHING, 125 cm tall. He has pale skin, short, tousled dark gray hair with bangs. He wears a loose light blue T-shirt, black shorts, and light-colored pants with sneakers. His eyes are dark, with a bright blush underneath.
Fanya, a 9-year-old girl, 143 cm tall, touchy, angry, whiny, sweet, and funny. She has long dark hair with bangs. She's wearing a beige sweater, a white shirt with a black tie, a dark plaid skirt, and beige boots. She has dark eyes and a rosy tint to her cheeks.
Kolya, a sweet, touchy boy of about 5 years old, with light, tousled hair and amber eyes. He's wearing a white shirt with puffy sleeves, a burgundy bow, dark shorts, black knee-high socks, and red shoes, with a blush.
