Wendy’s has introduced a Krabby Patty-inspired burger to celebrate SpongeBob SquarePants’ 25th anniversary, complete with a mysterious Krabby Kollab Sauce.

Wendy’s Adds Mystery to Krabby Patty Kollab Burger with Secret, Tangy Krabby Kollab Sauce

To celebrate the 25th anniversary of Nickelodeon’s animated classic SpongeBob SquarePants, Wendy’s has launched a unique Krabby Patty and a “Pineapple Under the Sea” Frosty, bringing an element of the show’s whimsical world to life. The Krabby Patty, central to the show as the sought-after burger of the Krusty Krab where SpongeBob works, has its own “secret formula” storyline that Wendy’s has creatively embraced.

True to its brand identity, Wendy’s brings its signature square patty to the Krabby Patty Kollab Burger, making it visually recognizable. According to Tasting Table, the burger, resembling Wendy’s famous Dave’s Single, features a quarter pound of beef with American cheese, lettuce, tomato, pickles, and onion. However, a unique off-pink “Krabby Kollab Sauce " sets it apart, reportedly reminiscent of French or Thousand Island dressing but with an added twist. Wendy’s keeps the ingredients under wraps, stating that the sauce contains eggs.

While Wendy’s hasn’t shared the recipe for the Krabby Kollab Sauce, the mystery has led to plenty of speculation. Some food reviewers liken it to a tangier version of Big Mac sauce, spiced up with extra pepper. TikTok reviewer and voice actor Stefan Johnson described it as similar to a Thousand Island-based sauce with a peppery kick, while other reviewers agreed on its bold flavor profile.
