When Fergie and Chouchou arrive separately in Fosterland, the two tiny babies have big challenges to overcome. But when they meet, friendship magic happens! They're two goofballs who cheer each other up with their wacky antics, to the entertainment of other fosters. But as they watch other foster babies graduate from Fosterland, they can't help but get discouraged. Healing takes time, but when will it be their turn?

What Fergie and Chouchou don't know is that the Elder Cats have been watching them. Coco, Eloise, and Haroun, who've always loved helping foster babies prepare for their forever homes, have lately been wondering whether it's time to retire to the sunroom and bring a new member or two into the fold. Could Fergie and Chouchou be the right fit to make Fosterland their Foreverland?
