First Sheri was fascinated with monkeys and used a familiar Alpine singing instructress as her logo. Then she became obsessed with cavies (Dolichotis salinicola and D. patagonum, I think) so I whipped up Cavygirl. Recently she switched to penguins and I replied with La Pingüita as well as the potentially offensive Penguin Family Singers (don't blame me, blame some dinner theater set designer).
Just call me the poor gal's Max Ernst.
