Twilight Imp

Wow it's that Twilight Imp, some kind of Midna perhaps.
She's helped out the farms in this alternate timeline it seems, purely to try out a new body that fills her with confidence and powerful magic. Augmenting the cows on the ranch to produce heavier, richer milk that is then refined even further into a powerful, fulfilling cream..

She wobbles and jiggles, challenging flustered onlookers to see how much larger and taller she will blossom.
