The group did it to honor SpongeBob Squarepants creator Stephen Hillenburg, who died in November.
Maroon 5 showed SpongeBob SquarePants some love during their halftime show performance at Super Bowl LIII.
In a tribute to SpongeBob creator Stephen Hillenburg, Maroon 5 included a segment of "Sweet Victory" during their 30-minute set and fulfilled the wishes of more than 1.1 million of the show's fans.
Hilleburg died in November due to complications with ALS.
Prior to the show, a Change.org petition urged the band to break out SpongeBob's Bikini Bottom Bubble Bowl anthem. Maroon 5 seemed to confirm SpongeBob's appearance with a teaser video that featured the character for about 32 seconds of the clip.
Here is the original performance.
The band also performed "Harder to Breathe" and was joined by Travis Scott and Big Boi.
