Mrs. Brannigan

Miss Brannigan is Coop's female math teacher. She is a young woman who appears in Coop's school. The closed captions for You Kat See Me spell her name Ms. Branigan when Burt says her name on the phone and later on. She has long blonde hair tied back into a pony tail by a purple thing, possibly a hair band or clip or scrunchee. Her eyebrows are dark blonde or maybe even brown, while Fiona's are black. She has blue eyes and facial freckles, like the blonde ponytail, also things which Fiona possesses, possibly indicating Coop and Dennis have similar aesthetic taste in women. The teacher's freckles are fewer though, 3 above her nose between her eyes, compared to Fiona who has 4 under each eye for 8 total. She has a small round nose like Coop and Millie (Burt's is larger and more oblong) while Fiona's is pointy. She has worn a dark red fully skirt (less pink skirt below) and possible an white T-shirt inside. She first appeared in "Me-Oh Me-Oh Meow" when Coop was in school wearing Kat's Special collar on his leg in her class. In "Curse of Tutankitty's Tomb" her last name was revealed when she was touring the class with Burt in a museum.
