Hmm Well for the middle (Calliope) I wrote a crossover poem for her and Kale, Sinbad's first mate.
For the lady to the left of Calliope, she always seemed really bubbly and uplifting. Miguel could work nicely for her.
To the right of Calliope, I never really got a character feel for her but since she seemed kinda subdued, perhaps someone with a funny, uplifting personality would do, like Genie!
