Microwave butter and marshmallows in large microwaveable bowl on HIGH for 1 + to 2 minutes or until marshmallows are puffed. (As an alternative, you can use the stove top as long as there is close supervision!).
Stir in gelatin until well mixed.
Pour marshmallow mixture over popped popcorn and candy corns in a large bowl.
Mix lightly until well coated.
Shape into about 15 balls, or other shapes, with greased/buttered hands.
If not serving immediately, wrap each ball individually in plastic wrap after they have completely cooled.
Make lines on orange balls like a basketball, and serve on a "fake" court with hoop.
