I understand what you're saying...but I didn't have that issue. In my mind it is almost "sing/song" how it rolls off the tongue...but I need to try and see it from a customer's POV.
How 'bout this:
Getulas & Gutattas:
Captive Bred Snakes
And have a picture of a king and a corn. Would that be more clear? I also hope to be able to spark someone's curiosity, and invite questions...
