April revealed her age in the Season 3 episode "Leather Head - Terror of The Swamp". In Florida on vacation, she and the Turtles found a body of water contaminated with a mutagen that made mutants feel youthful, while physically de-aging humans into four-year-old versions of themselves. Donatello did not allow April to enter the water, to which she lamented, "Oh, great! I'm doomed to be a decrepit twenty-eight-year-old hag!" Her Aunt Agatha ("Aggie"), who appeared in the episodes "Case of the Hot Kimono" and "Sleuth on the Loose", was a detective.
