Happy birthday, Stormi!

Kylie Jenner and Travis Scott threw a low-key birthday party for daughter Stormi's first birthday on Saturday -- the event was postponed from a previous date due to rain. They rented out a warehouse, had a custom inflatable of Stormi's face, the entire interior of amusement games were custom-made for the tot, all based on Kylie's "dream." Simple and age-appropriate, right?!

The Lip Kit maven and her rapper hubby created #StormiWorld -- a play on Scott's Astroworld album name -- in honor of their baby girl. There was a ball pit, a life-size spinner wheel, amusement rides, Louis Vuitton-inspired French fries, and even a "Baby Shark" performance.

Kylie wrote on Instagram: "I had to go all out for my baby." Uh, yeah!
