North West is another year older!

It's unclear whether North will have a blowout bash this year amid the ongoing coronavirus pandemic. (She and Penelope often have joint birthday parties.)

Last year, North and Penelope celebrated their birthdays at a joint Candy Land-themed bash. The cute cousins frolicked among a colorful sweets explosion in Kourtney's backyard, as revealed a post on her lifestyle website Poosh, wearing coordinating rainbow outfits and indulging in a variety of treats from Sugar Factory.

"In Kourt's backyard, a massive rainbow pathway led to the Candy Castle: a life-size gingerbread house that was filled floor-to-ceiling with candy from Sugar Factory," the post shared. "Kids could fill reusable bags to the brim with peach rings, gummy bears, sugar tape — you name it."

Other details at the sunny outdoor soirée included tons of colorful balloons, a Dragon's Breath dessert (complete with smoky liquid nitrogen!) from Supercool Creamery, a lunch spread from Bludso's Bar & Que, a "candy bounce house," face painting and even a station where kids could design their own "candy sunglasses" courtesy of Gap Kids.

"A lollipop road paved the way to a candy costume playhouse, where kids could dress up as their favorite piece of candy," the post explained of another unique touch. "Costumes from Chasing Fireflies and HalloweenCostumes.com turned children into Tootsie Rolls, candy princesses, cotton candy and pieces of Bazooka bubble gum."
