As our first year entering the our city parade, I think we did a pretty good job. We were towards the back of the parade (there were close to 70 floats) and still pulled off a 2nd place finish in the originality category.
The idea behind the float was lovingly dubbed “Frosty’s revenge”, using white-painted poof balls as snowballs and dressing up our 2006 robot as Frosty the snowman.
The small robot on the left was cobbled together from spare parts and a Fisher-Price car. We mounted our mascot to the unsteady top of the robot, wobbling crazily whenever we switched directions (made it a crowd favorite). We had 46 different versions of the classic frosty song jamming out of a speaker set up front, as to not drive everyone crazy, and everything worked out very well.
