Camp Lakebottom
Gretchen (voiced by Melissa Altro): She is a girl who is described as being anything but "sugary sweet"; she is sardonic and indifferent about everything as well as a tomboy. Her lack of enthusiasm is made up with her sharp, critical tongue. With a black belt in karate, and an intolerance toward wrongdoing, Gretchen is not a girl to mess with. Her nemesis is Suzi. However underneath the tough exterior she has a huge heart, and secretly wishes she could be like any normal girl (though she would never ever reveal this). Her catchphrase is "Ya think?!" usually said to McGee when a plan has gone away and he points out the obvious. She is revealed to have a severe phobia of chipmunks in "Cheeks of Dread". Her dad calls her "Gretchikins" and her mom calls her "Gretchywetchy". Gretchen is nicknamed "The Gretch" and her parents have the surname Gritcherson.
