Aunt Eunice is George and Junior's Great-Aunt (but whom the whole family calls 'aunt'), who sometimes serves them as their babysitter. The first time she watched the boys, she was very patronizing toward George, treating him as though his size were a handicap and "assisting" him. However Aunt Eunice's ways have changed when George fixes her prized plant, a Bonsai tree "Maurice", which seemingly been damaged beyond repair. In "Return to Sender", she expresses complete confidence in that George will handle himself just fine when he was mailed to various locations across the planet, and that he could mail himself back home safely. She has travelled around the world; as such, she knows a great deal about different places as well as people. The boy's mother, Perdita Shrinks, is Eunice's niece. She is voiced by Catherine Gallant.
