     Lee drank a potion that helped him to breathe underwater. Beardy then told me I could turn into a merman and Holly could turn into a merdog (like in an old book I've written). So I soon turned into a merman and Holly turned into a merdog.

   • 2011, Judika Illes, Encyclopedia of Mystics, Saints & Sages:

     Rather than the flayed skin associated with the traditional saint, this Saint Bartholomew holds a sword or trident. Something rests beside his feet—it may be a demon, dolphin, or merdog. This creature is Bartholomew's messenger and servant.
