A scent-dispensing device that dispenses scent while the device is pulled through water comprises a cylinder of uniform diameter with a first end and a second end A piston is movably positioned within the cylinder, such that when the body is pulled through the water, water enters the first end of the cylinder and causes movement of the piston toward the second end of the cylinder. As the piston moves toward the second end of the cylinder, scent is forced through the second aperture and into the ambient environment.
