I love the inventiveness of this Toilet Bowl Costume from Carolyn Terlet.
It looks like a Porta-Potty connected to a white box. Add a white mask, turtleneck and leggings for the finishing touches. They used a flushing handle made out of aluminum foil and a clothes pin, but a REAL toilet handle is pretty easy to come by at the hardware store, so I’d go that route.
According to Carolyn, the candy went in the toilet bowl. Brilliant!
