Her (nick)name is Sheepy?... i mean, is quite close to the name tag than, well... Froggy Nun/Hook-bang Nun, but still. Should we change the name tag to Sheepy?

Sheep Nun: "I exist primarily as a supporting character for Froggy. I love the little Hook-Bang but I really wish that Master Diva would finally give me some individual spotlight, like my own arc for example."
