Water needs a sea snake for sure. Hmm I wonder if they'll go for anacondas for any flight. Maybe nature?

I was thinking a milk snake (or coral, or kingsnake- similar coloring) might suit shadow in a sideways way since it reminds me a bit of casino colors and the circus/casino theme they have going on for trickmurk.

I was thinking about sand boas earlier. So majestic:
