We claim the ornamental design for a hoop toy, as shown and described.

FIG. 3 is a left side view thereof, the left side view being a mirror image of the right side view;
FIG. 4 is a top view thereof;
FIG. 5 is a bottom view thereof;
FIG. 6 is a top perspective view thereof;
FIG. 7 is a front view thereof; and,
