Dina
Based on the character from Undertale Yellow, a reimagined, "bottom-heavy" Dina would emphasize her armadillo-like armor plate, making her appear much wider and more shapely from the waist down, with a notably heavier, rounded rear-end that sways as she walks behind the bar. Her tan, scaly skin would be accented by this added girth, and she would move with a slow, deliberate confidence.
Here is a description of this reimagined Dina:
Appearance: She retains her reddish-purple hair and large, affectionate tan ears. The red armadillo chestplate she wears now appears as a tight, cinched corset that emphasizes a heavy,, hourglass bottom-heavy figure, with the carapace plate extending over a much plumper, rounded rear-end. Her reddish-brown tail is thick at the base and occasionally thumps on the floor while she works. She still wears her signature green snakes—Ann, Sammy, and Bert—draped lazily over her shoulders.
