Quilpie, voiced by Katie Bergin is a kangaroo and Mooseknuckle's courier. She speaks with an Australian accent, wears a blue courier's uniform, and has blue eyes and blonde hair tied back. She is extremely punctual, and does not like for anything to be late. She seems to be rather eccentric, as in "Petition Impossible", Zoop asked her to wait a few more minutes when she became impatient while waiting for Iggy and Jiggers to give her the petition but Quilpie told her that would disrupt the delivery schedules, and went on a fast-paced, step-by-step concept of what exactly might happen. Quilpie can later be seen in "Koo Koo Achoo". She was in the lineup to buy the bobbleheads which Jiggers had carved, but did not receive any lines.
