Hoops would always play Basket with Marble, and she really enjoys it! So as for them, they start a family more in the future, Marble did get pregnant by accident, still both where a bit surprised but happy to make a family.
Pinkie was REALLY over protecting Marble when she first met Hoops (She didn't like him for her sister because he was a bully)
So i did a fanart for both, also using my headcanons for them (markings and stuff)
