Izzy had had enough of Sprout being racist toward her for being a unicorn, even post-reunification, so she took this matter of vigilante justice into her own capable hooves… or should we say, into her own capable stomach.
Hitch was quick on his trail to find out where his ex-deputy, who was supposed to be in custody after he started a race war and wrecked Sunny’s home, disappeared off to - but Izzy’s metabolism was quicker. By the time Maretime Bay’s sheriff showed up, Izzy’s powerful body had already finished absorbing the last traces of what used to be Sprout, leaving her looking as cute and slender as usual.
Hitch did notice that his purple friend was taking a certain interest in her own belly, almost as if she was impressed by it - maybe she was just hungry? Perhaps he’d treat the friendly unicorn to lunch and pick her brain about Sprout’s whereabouts over a nice meal.
