Chumley was an alligator snapping turtle who served as one of Mz. Ruby's servants. During her battle with Sly Cooper, Mz. Ruby had Chumley escort him over to her position while she attacked Sly with her voodoo magic. Sly managed to dodge all of Ruby's attacks, the final of which struck and killed Chumley.
Chumley's appearance was similar to that of the fire turtles. He was rather small-sized, but large enough for Sly to stand atop his back. Despite being an alligator snapping turtle, Chumley bore the flippers of a soft-shelled turtle.
