Khloe Kardashian and her ex Tristan Thompson marked their son Tatum’s 4th birthday with an elaborate celebration, which saw the Kardashians star transform her home into a Zootopia-inspired wonderland, complete with a petting zoo and life-size characters.

In clips shared to her Instagram Stories July 28, the 42-year-old showed off the personalized signage that welcomed party-goers to “Tatumtopia” with the Disney film’s characters beckoning guests.

Inside the house, Kardashian—also mom to True, 8, with the former NBA star—introduced Tatum to the real-life mascots, who he hugged and smiled with as he posed for pictures.

The Khloe in Wonderland podcast host also gave a house tour—which included a guest appearance by mom Kris Jenner—to showcase the “gateway” to the “kid party,” complete with a bunny rabbit petting zoo, a stuffed animal-making station, a squishy-making station, a kiosk where kids could pick their own animal ears and a Tatumtopia themed food and dessert station. 

The birthday party also served as a 20th birthday celebration for Kardashian’s brother-in-law Amari Thompson, to whom she serves as a caretaker as he lives with Lennox-Gastaut syndrome. In fact, both birthday boys had their own 5-foot-tall, Zootopia-themed birthday cake.

And as the Good American founder explained, she was willing to do “anything for a 4-year-old and a 20-year-old, my Amari and Tatum.” 

The day before, Kardashian celebrated her “sweet angel” Amari’s birthday with a special tribute.

“Some people change the world with their words. You change it simply by being you,” she wrote on Instagram July 27. “Your heart, your spirit, and your light say everything that words never could.” 

“You are one of God’s gentlest reminders of what truly matters,” Kardashian continued. “Everyone who knows you is better because of you. Thank you for reminding us every single day how we should be so completely grateful for the smallest of things and what unconditional love, joy, grace, resilience, and gratitude truly look like.”
