If you've ever spent a Saturday morning staring at a cartoon sea sponge flipping burgers, you've probably wondered what a Krabby Patty actually tastes like. For years, the "secret formula" was the holy grail of Nickelodeon lore. Then Wendy's stepped in.
In late 2024, to celebrate the 25th anniversary of SpongeBob SquarePants, Wendy's launched the Krabby Patty Kollab Meal. It wasn't just a toy in a box. It was a full-blown menu takeover. But what exactly was in the bag, and did it live up to the hype of a sandwich that once made Squidward eat so many he exploded?
Honestly, it depends on how much you like "secret sauce."
The Anatomy of the Krabby Patty Kollab Burger
Let’s get the big question out of the way: Is there crab in it? No. Never was. In the show, the ingredients are a mystery, but Wendy’s stayed true to their own roots while trying to mimic the look of the Bikini Bottom staple.

Basically, the Krabby Patty Kollab Burger is a modified Dave’s Single.
It starts with a quarter-pound of fresh, never-frozen beef. That’s the Wendy’s signature. They top it with two slices of melted American cheese—standard, but effective. Then comes the garden: crisp lettuce, a slice of tomato, crunchy pickles, and onions. All of this sits on a toasted premium bun.
The "Kollab" part is really about the sauce.
Instead of the usual ketchup and mayo combo you find on a Dave's Single, Wendy's swapped it for a Top-Secret Krabby Kollab Sauce.
Breaking Down the Secret Sauce
Wendy's kept the official recipe under lock and key, much like Mr. Krabs. However, because of allergy disclosures and some very dedicated food sleuths, we know a lot more than they probably intended.
- The Base: It's a mayo-heavy sauce.
- The Tang: It uses tomato concentrate (ketchup-adjacent) and distilled vinegar.
- The Kick: There's a noticeable hit of cayenne red pepper and paprika.
- The Umami: This is where it gets interesting. Reports from employees and ingredient labels mentioned "Rochester sauce concentrate," which is very similar to Worcestershire sauce.
If you tasted it and thought "this is just Thousand Island," you aren't entirely wrong, but you're missing the nuances. It’s zestier. Some people compared it to Raising Cane’s sauce but with a sweeter, more peppery finish. It’s got that "fry sauce" energy but dialed up for a burger.
Pineapple Under the Sea Frosty: The Tropical Twist
The meal isn't just a burger and fries. The real standout for many was the Pineapple Under the Sea Frosty.
Usually, Wendy’s is a chocolate or vanilla house. For this collab, they didn't just change the flavor of the mix. They used a Vanilla Frosty base and swirled in a pineapple-mango puree.

It wasn't a blended shake. It was a swirl.
If you were lucky, you got a cup where the golden puree was drizzled along the sides and pooled at the bottom. The flavor was intense—very tropical, very sweet, and it actually smelled like fresh mango the second you took the lid off. Some fans complained the puree was a bit too syrupy, making it hard to get a consistent flavor in every spoonful, but when you got a "perfect" bite, it was arguably the best part of the whole meal.
The Sides: Just the Classics
You might expect "Seaweed Fries" or something themed, but Wendy’s played it safe here. The meal came with their standard Natural-Cut Hot & Crispy Fries, seasoned with sea salt.
They didn't mess with the fries.
Why? Because Wendy’s spent years marketing their "Hot & Crispy Guarantee." Changing the fry recipe for a promo would have been a logistical nightmare and probably would've annoyed the people who just wanted their salty potato fix.

Is It Still Available?
Here is the cold, hard truth: the Krabby Patty Kollab Meal was a limited-time offering.
It officially hit menus on October 8, 2024, in the U.S., Canada, and Guam. Most locations stopped serving it by mid-November 2024. If you walk into a Wendy's today and ask for a Krabby Patty, you'll likely get a confused look from a teenager behind the counter.
That said, the "secret" isn't actually that hard to replicate.
How to "Hack" a Krabby Patty Today
If you’re craving that Bikini Bottom flavor and the promo is long gone, you can get 90% of the way there with a custom order.
- Order a Dave’s Single. 2. Ask for no ketchup and no mayo. 3. The Sauce Hack: Since you can't get the Kollab sauce, the closest substitute is a mix of mayo, a little ketchup, a dash of Worcestershire, and a pinch of cayenne or black pepper.
- The Frosty: Buy a Vanilla Frosty and stir in a spoonful of pineapple preserves or mango nectar.
It’s not perfect, but it hits the nostalgia buttons.
The Wendy’s Krabby Patty wasn't just about the food; it was about the fact that for twenty-five years, we've wanted to be part of that world. The meal gave us a quarter-pound of nostalgia with a side of tropical soft-serve.
If you want to stay ahead of the next big fast-food drop, keep an eye on the Wendy’s app. They tend to load their biggest "surprise" collaborations there first, often with mobile-exclusive discounts that make the $12 price tag a bit easier to swallow.
Check your local Wendy's rewards balance to see if any "legacy" sauce packets are still floating around—you'd be surprised what stays in the back of the fridge.
