A toy includes a body and an appendage system at a side of the body. The appendage system includes an arm and a linkage. The arm includes a first end fixed to rotate in a circular path and a second unfixed end. The arm defines a slot extending between the first and second ends. The linkage includes a linkage rod that is engaged with the slot. The linkage is positionable about a linkage shaft coupled to the body. Rotation of the first end of the arm causes the second unfixed end of the arm to move in a non-circular path that varies depending on the position of the linkage about the linkage shaft.
