The Heirs of Clan McDuck

Scrooge McDuck though he'd lost everyone that fateful day. Then, he finds the one egg Donald didn't take. A couple of months later, on his doorstep, he finds his ex, former partner, and a pink-bowed bundle of joy who has his eyes. Or, my Quadruplets AU combined with the Webby O'Gilt AU by neopuff, heavily inspired by NatureWitch21's 'A Different Tale'
