Edna Turnbuckle is one of the suspects in Scooby-Doo! Jinx at the Sphinx. She is a tourist from Kansas.
She is a middle-aged woman with grayish brown hair, wearing sunglasses, a hat with a feather adorning it, a yellow shirt and short pants.
In one possible ending, she dressed up like a mummy with her husband, Bob, to steal treasure. But the clues she and Bob left for Mystery Inc. to find led to their arrest, and the couple were forced to return to Kansas.
