The ornamental design for seamless fuzzy hanging dice with on/off vehicle plug-in switch, as shown and described.
FIG. 1 is a perspective view, taken from the top and left/front side of my novel vehicle dice shown engaged with a car mirror, or other like hook/nail for hanging the fuzzy dice from another surface; and,
FIG. 2 is another perspective view, taken from the bottom and right/rear side of my fuzzy dice.
The broken line showing of environment is for illustrative purposes only and forms no part of the claimed design;
The cord is shown broken away in FIGS. 1 and 2 to indicate indeterminate length.
