Kim Kardashian and Kanye West threw their daughter North an extravagant birthday party yesterday at Kourtney's Calabasas home, and from the ferris wheel to the stage, they really went big!

The bash was inspired by Coachella (they called it "Kidchella"), and the Kardashians asked that guests dress like they would at the annual California music festival. Khloe went all out with a Native American headdress while Kendall and Kylie wore shorts tops that probably didn't make the cut this year when they packed for the party in the desert.

Kendall and Kylie spent quite a bit of time lip-syncing songs on the mini-stage (mom Kris Jenner posted videos of them rocking out to Rihanna's "We Found Love" and Kanye West's "Good Life"), and there as also a big bounce house and food stands.

"Kim was holding North a lot of the time, and the party seemed to be geared towards a little bit older kids," an eyewitness tells Us Weekly. "But it was a family party with all ages, and no matter what age they were, they were having a great time. There was so much to do." We're not sure who planned this, but it does look pretty awesome!

Khloe posted the photo of herself above with the teepee and wrote, "Ray of clouds. Chirping of birds. Gurgling of water. Granting desire. One with water. #Kidchella, my first Coachella!!!" Check out the gallery below for more photos!
