With the help of creative communications firm Small Girls PR, the celebration took place at Chain House, a Los Angeles pop-up known for reimagining fast food.
The guest list included Snapchat’s Ghostface Chillah, Yo Gabba Gabba, Charlie the Tuna, and Try Guy Keith Habersberger.
John Legend led the room in singing "Happy Birthday," while Chrissy Teigen popped out of a cake.
Chain House CCO Nicholas Kraft shared with DesignRush that the team embraced an offbeat party aesthetic, with guests dancing "under a Jack-shaped disco ball while the DJ booth broadcast the iconic JITB commercials."
"So we asked ourselves what would a Jack-inspired party would look like, and the answer was 'tastefully unhinged.'
The menu offered a playful twist on classics, including wagyu tacos, caviar-topped curly fries, and a Skrewball peanut butter whiskey slushy.

Small Girls PR CEO and Co-Founder Mallory Blair told DesignRush
"This time, the magic happened when we pitched to invite iconic mascots to celebrate Jack Box's birthday.
What started as a private event turned into a highly shared cultural moment that got everyone talking — the Met Gala of mascots, if you will.
It's a good example of how the right creative input can turn brand news into earned media fodder and how embracing collaboration over competition can halo attention beyond typical audiences."
This event shows how creative agencies can drive wider impact by inviting unconventional guests and building collaborative moments that naturally attract attention.
From Apps to Apparel
To extend the impact beyond the party, Jack in the Box launched a limited-edition merch line, featuring themed shirts, stickers, and a magnetized replica of Jack’s iconic yellow hat.
The collection was available exclusively online and promoted across Jack’s social channels.
Limited drops like this create urgency and turn short-term events into long-term brand touchpoints.

The app-based promotions created daily incentives, offering free tacos, nuggets, sandwiches, and egg rolls with qualifying purchases.
Combining pop culture, product giveaways, and creative collaboration allowed Jack in the Box to turn a mascot’s birthday into a widely shared cultural event.
In doing so, it raised the bar for what restaurant marketing can look like.
