Some shots of her cleavage were considered to be too much for a children's cartoon, and as a result, were air-brushed out. Her second and last solo short, 'Moon Over Minerva', was slightly edited for content before broadcast. Additionally, many of the zany wild-takes on part of the male cast members were filled with innuendo. For example, on one occasion, Minerva was seen as a shapely, nude silhouette while bathing in a lake. Minerva starred in the least number of shorts of all the ensemble cast, allegedly on account that the content of her shorts was so overtly sexual that it was decided that it would be inappropriate for the intended predominantly children's audience. When she spots an attractive male, she goes into multiple lustful spasms of her own like the ones the males give her.

However, her final concept was for her to drive every male, no matter their species, into wild take-filled Tex Avery-styled conniptions at her beauty. Minerva was created with an initial thought of reversing the gender on the Tex Avery Wolf, who would go into extreme wild takes when he saw a particularly hot female. However, she was most often shown the same size as human beings, only about a head shorter than Hello Nurse. In her first appearance she was shown to be the size of a normal mink (this is in relation to her size compared to Newt, who was shown earlier in that episode only coming up to his master's knee). In addition, appearance borrows from many famous sex symbols, most notably Veronica Lake, whose sheepdog haircut is similar to Minerva's style. Being a 'fashionable' girl, she is rarely seen wearing the same outfit twice, though most production art shows her wearing a red jumpsuit.

Minerva has white fur with long blonde hair, an enormous soft blonde tail as well as a pretty face, pink nose and sweet big black eyes with blue eye shadow. WBTA's management felt this 'al fresco design' was inappropriate for family entertainment, with final designs and name change occurring prior to the first Minerva episode airing.

Her initial design had her naked, very much like Slappy Squirrel’s younger design in the episode “Buttermilk”. She, much like Hello Nurse, is designed to be 'attractive' (she also gets similar reactions from male characters as Hello Nurse).
