I tend to take a long while to name most of my animals to find just the right name. So many still not named.
His "emoji" marking on his tail is pretty cool and looks like it's changing moods depending on how his tail is bent but that may just be the particular camera angles. That might help think of something clever.
I think Lucifer is a really cool name but I wouldn't name a BP that because I would confuse myself and my family because of the morph Lucifer. What about something similar like Mephisto or Azazel or something?
Makes sense. His emoji marking is what finally sold the idea of getting a ball python to my boyfriend lol. Because you noticed it changing it makes me wonder if I should call him Jekyll or Hyde lol
