When they were looking in the bathroom of the WW2 Veterans house, twice they showed the toilet, which lookedto have something greenish/yellow in the bowl, and then they panned to the Trademark people who had a disgusting look on their face. If you looked closely, you could tell the green/yellow colors were some sort of CGI special effects that were added later. When the camera moved, the colors could be seen hovering and jiggling around, even though no one had flushed the toilet...

I thought Ginger tinkled in the toilet.

maybe it was a ghost turd.
