How Old Are ‘SpongeBob’ Characters in 2025?

Ever wondered how old your favorite character from SpongeBob would be in 2025? Here's what we know.
From Millennials to Gen Alpa, SpongeBob SquarePants has been a comfort show across generations. But have you ever wondered what generation SpongeBob and his friends would be in 2025? Well, we have some answers just for you!
Fair warning: take it with a grain of salt as we're sure that life in Bikini Bottom is very different from ours. And what age means to a sponge or King Neptune anyway?
SpongeBob SquarePants
Age in 2025: 39.
If you've paid close attention to the earlier episodes, you might have caught a glimpse of SpongeBob's driver's license. In “Sleepy Time” and “No Free Rides,” his birthdate is clearly shown as July 14, 1986.
As he approaches his 39th birthday this summer, we can't help but wonder if Mrs. Puff will finally let him have his boating license as a birthday present.
Pearl Krabs
Age in 2025: 35.
In “Whale of a Birthday” Pearl celebrates her 16th birthday. The episode came out back in 2006, which means that in 2025 Pearl should be 35 years old! Just imagine Pearl dealing with adult whale problems instead of teen drama.
Bubble Buddy
Age in 2025: 24.
Created by SpongeBob in the episode “Bubble Buddy” which aired in 2001, this soapy friend would be 24 years old in 2025. Pretty impressive lifespan for a bubble! Must be that special Bikini Bottom formula. We wonder if he still pays with bubble coins.
Mr. Krabs
Age in 2025: 83 or 65.
When it comes to Mr. Krabs, things get a bit confusing. In “Sleepy Time,” Mr. Krabs' license shows he was born on November 30, 1942. But wait in “Mall Girl Pearl,” his license suddenly indicates a birth date of September 25, 1960.
Maybe our boss altered his ID to appear younger? It would be such a Mr. Krabs move!
Plankton
Age in 2025: 83 or 65.
Once best friends turned rivals, Plankton and Mr. Krabs share the same birthday as revealed in the episode “Friend or Foe.”
King Neptune
Age in 2025: 5,015.
In “The Clash of Triton” (2010), King Neptune celebrated his 5,000th birthday. That puts him at a whopping 5,015 years old in 2025. And guess what? He's celebrating another anniversary this year! Maybe immortality is the real treasure of the sea.
Barnacle Boy
Age in 2025: 91.
In an episode ”Mermaid Man and Barnacle Boy V” (2002), he was already 68 years young and was annoyed with Mermaid Man calling him “Boy”. Now at 91, this must be even more annoying.
Flying Dutchman
Age in 2025: at least 5,000+.
The Flying Dutchman mentioned in “Your Shoe's Untied” that he hadn't worn shoes for 5,000 years. By 2025, this ghostly pirate is well over 5,000 years old. That's a lot of time spent haunting the seven seas and collecting souls.
