Yep, Tictac loves Sweets, it fits a sweet chubby Morpeko girl like her also she only got Pregnant when she and Zach (her Pawmot Husband) were sitting right beside a Picnic Basket and Joseph (aka Me) was eating an Egg-power sandwich, due to the Paldean Picnic basket being magical, it caused an egg to form in Tictac’s body, and the picnic basket can form eggs into Married female Pokemon with just its magical aura, Tictac didn’t feel so good after that and became her hangry mode and needed to consume sweets, one week later, Minty was born (It’s a scarlet and violet reference look up that game’s breeding mechanic) (Also I’m not trying to imply anything weird it’s normal)
Also no, she did not eat all that food in one sitting, it was over the course of a week so once again, DON’T FAT SHAME HER! She was only fat for 1 week and 5 days after Minty’s birth (the cravings still lingered after she laid her egg) Also the cakes were Strawberry Flavored, it was also Valentines season around the time Minty was born
