Caitlin is a guest judge and recurring character on Animal Crossing: Model Mania.
Caitlin is a plucky brunette who first appeared in Episode 8 of AC:MM. She is the first guest judge of the series to be shown among the cast, and to have consecutive appearances (showing up in Episode 9 and 10.) Not much is known about her, but she knows how to drive an RV and may or may not be an official security guard.
Caitlin's judging role is done by Animal Crossing Community user czarblue10. Her birthday is August 26, just like czarblue.
