The Toad and the Vixen: InsectivoreShipping hatchlings

After getting married after being together for so many years, Ash's Greninja and Serena's Braixen have kids together. They had their litter. First came their firstborn son Froakie, and then a pair of Fennekin twins (Fennekin 1 and Fennekin 2). After a while, Greninja and Braixen decided to have more kids, and then, they have their second litter. Firstborn was Shiny Froakie, being followed by Shiny Fennekin four hours later.

Personality
Froakie: The firstborn son of Greninja and Braixen. Being the oldest, he always has this opportunity to look after his younger siblings when needed. He likes to be with his father and Greninja is always teaching him some pretty cool things and moves. Froakie is adventurous and audacious, and he's also very supportive, selfless and helpful, and always puts others before himself. He also likes to be with Michelle.

Fennekin 1: The older twin. Fennekin 1 is very hyperactive and outgoing. She's also a huge momma's girl, always sticking close to Braixen and spending time with her. She's also much of a chatterbox, and is always seen talking, until either Froakie or Michelle correct her. Though she's very nice and caring, and never wants to make people sad.

Fennekin 2: The younger twin. Fennekin 2 is the opposite of her sister. She's really shy and quiet, and not seen talking but only speaking a word or two. She's mostly Daddy's girl, and doesn't like letting people down. She's also very calm, and is rather seen playing than battling.

Shiny Froakie: The firstborn son of the second litter of Greninja and Braixen. Froakie loves going to the park and play with toys and with his big siblings. He's a huge momma's boy like his big sister, Fennekin 1. Like his brother, he also likes to hang out with his father, and wants to be just like him one day.

Shiny Fennekin: Younger than Shiny Froakie by 4 hours. Like her sister, Fennekin 2, Fennekin is really shy and quiet, and since she's very, very quiet, she's rarely seen talking except for a word or two. Fennekin is also carrying around a plush version of her mother.
