Abstract
A toy includes a magazine and a movable arm having a launching end. A plurality of disks are configured to be stacked face to face in the magazine, where each disk has a recess in its face and an engagement element near an edge of the disk. The launching end of the arm includes a retractable extension that is insertable into the recess in the disk, such that the arm is capable of receiving the disk. A protrusion on the magazine engages the engagement element in the disk, causing the disk to rotate around the retractable extension as the arm removes the disk from the magazine. A mechanism in the arm causes the retractable extension to protrude when the arm is adjacent to the magazine, and to retract to release the disk when the arm is moved away from the magazine.
