Celebrity Parents Yabba Dabba-dorable! Kim Kardashian and Kanye West Rock Family Flintstones Costumes on Halloween Kim Kardashian West went as Betty Rubble while Kanye West dressed as Dino and their kids channeled Wilma, Pebbles, Bamm-Bamm and Fred Flintstone By Jen Juneau Jen Juneau Twitter Jen Juneau is a digital news writer for PEOPLE since 2016.

Kim Kardashian West and her brood went all out for Halloween this year, topping off their already-impressive array of ensembles with a group costume that blew the top off of Bedrock and beyond: The Flintstones! Son Saint, 3½, and daughter North, 6, led the group as Fred and Wilma Flintstone, respectively, while their 21-month-old little sister Chicago donned a red wig with a faux bone as their daughter, Pebbles. Then came Kardashian West, 39, looking perfect as Betty Rubble with a tiny Bamm-Bamm in her arms — expertly played by 5-month-old son Psalm. Arguably the most committed to his character? Dad Kanye West, who was completely covered by a head-to-toe Dino costume to portray the Flintstone family pet as he posed with his wife and children against a prehistoric backdrop.

LOL We tried to explain and show her that it was just daddy but she didn’t get the concept yet! So shout out to the photographer for editing her in & making our family [Flintstones] dreams come true!” Kardashian West captioned her family snapshot. She wrote alongside two other slideshows of photos showing off the group’s fun outfits, “Flintstones 🦴” and “Yabba Dabba Doo!” From L to R: North, Chicago and Kim Kardashian West.

On Thursday, the Keeping Up with the Kardashians star and beauty mogul — who’s studying to be a lawyer — unveiled the first of her inspired get-ups, where she channeled Elle Woods from Legally Blonde. As for daughter North, the little girl had already joined her cousin Penelope Scotland, 7, and a pal as a devil (for North), and angel (for their friend) and a creative in-between option (for Penelope). “👹 or 👼🏼,” Penelope’s mom, Kourtney Kardashian, captioned the adorable shot.
