I wasn't joking about Ruby's favorite scent being earthworm, her all time favorite place to roll and rub is on a dead worm. She also loves to writhe around on the bed pillows, pushing up under them as she wriggles. Reno will writhe around too, but more as part of playing with him, than just on his own.
