North, 4, and 5-year-old Penelope wobbled across the wooden floor in too-big heels as little North gushed about a supposed party the cousins (and best friends) were planning to attend.
“We going out to go to a party!” North told her 36-year-old mother. “We’re going to our party! It has balloons!”
Penelope chimed in: “It has mermaid cake! We are going to be the mermaids and there is 97 mermaids.”
Ever the doting mother and aunt, Kardashian West played along with the eager girls, saying that Penelope looked “divine.”
North and Penelope, the daughter of Kourtney Kardashian, are likely still in party mode since their Moana-themed joint birthday bash in late June — and little Penelope rang in her fifth year on Saturday.

On Penelope’s big day, Kardashian West uploaded a sweet photo of the girls cuddling close while dressed in similar outfits.
“Happy Birthday my sweet P!” Kardashian West captioned the picture. “Thank you for being the best friend to my North! I love you!”
