Joanne Vannicola as Huckle Cat, Sally's older brother and the leader of his detective group. Huckle is the most mature, observative and intelligent of his group, though he isn't above childish behavior. He drives a red car with a picture of his face on the hood. • Ellie Ellwand as Sally Cat, Huckle's younger sister. Sally is much more immature than her brother, but she is always on his side. She rides an orange scooter and wears a red helmet doing so. • Paul Wensley as Lowly Worm, a friend of Huckle and Sally's. Lowly is easy going and has a bit of a joking spree, often disguising himself as a long and thin object. A running gag in the series is Lowly's penchant for sneezing when near something he's allergic to (often a flower). He drives a red car shaped like an apple. •
Julie Lemieux as Pig Will, Pig Won't's twin, and a friend of Huckle's. Pig Will is cheery and optimistic, and although he and his brother mean well, their penchant for ridiculous theories, focus on food, and constant arguments often serve as a common source of the group's annoyances. He and his twin share a truck with a cab shaped like a sausage. Pig Will is identified by his straight ears, green shirt, and higher-pitched voice. • Lemieux also voices Hilda Hippo, a friend of Huckle's.

She has numerous activities and drives a pink and purple buggy. • Richard Binsley as Pig Won't, Pig Will's twin, and a friend of Huckle's. Pig Won't is grumpy and pessimistic, and although he and his brother mean well, their penchant for ridiculous theories, focus on food, and constant arguments often serve as a common source of the group's annoyances. He and his twin share a truck with a cab shaped like a sausage. Pig Won't is identified by his bent ears, red shirt, and lower-pitched voice. • Kevin Dennis as Goldbug, Busytown's main reporter. He is often around when there is a mystery around, but he also does reports on key events all over Busytown.
