The Cake is a Waifu (Patreon)

Clypse excitedly looks forward to his birthday dinner with Volvautia, only to see a giant cake waiting for him at home. Where did she go? Yet before he can go looking for her, the cake rumbles and shakes before exploding as Mega FlareVautia growmerges! Cake showering the little Umbreon and coating her all over with yummy icing and pastry, all the while she giggles and holds up the real cake in her palm. “Happy Birthday my little shiny boy, now come eat your cake~” She croons.
