Aisha Tyler provided the original voice for Sextina Aquafina, the provocative dolphin pop star in the Netflix animated series BoJack Horseman. Tyler voiced the character during her initial appearances in Season 1 and Season 2. However, for the character's most prominent storyline in Season 3, the role was recast with actress Daniele Gaither.
Sextina Aquafina is one of the most memorable recurring characters in the BoJack Horseman universe, serving as a biting satire of the music industry and celebrity culture. While the character is a literal bottlenose dolphin, her persona mirrors the hyper-sexualized, trend-driven marketing often associated with teenage pop icons. Understanding Aisha Tyler’s contribution to this role requires looking at the early development of the series and the specific comedic timing she brought to the character before the role was transitioned to another performer.
The Evolution of Sextina Aquafina
Sextina Aquafina first appears in the second episode of Season 1, "BoJack Hates the Troops." In this introduction, she is established not just as a singer, but as a cultural force in "Hollywoo" (the show's version of Hollywood). She is represented by Princess Carolyn, BoJack’s agent and occasional girlfriend, which anchors her firmly in the show's professional ecosystem.
As of 2026, BoJack Horseman is frequently cited in academic studies of television satire for its ability to blend "animal puns" with devastatingly real human emotion. Sextina Aquafina represents the "absurdist satire" side of this equation. She is a dolphin who wears gold chains, records hit singles with titles like "Muzzle Toff," and communicates with a mixture of "valley girl" slang and literal dolphin chirps.
Aisha Tyler’s Contribution (Seasons 1 and 2)
Aisha Tyler is a veteran of both stand-up comedy and voice acting, best known for her long-running role as Lana Kane in Archer. When she took on the role of Sextina Aquafina, she brought a specific brand of "cool-girl" detachment that made the character’s vapidity feel authentic.
In Season 1, Tyler’s performance highlighted Sextina’s youthful arrogance. In Season 2, specifically the episode "Hank After Dark," Sextina’s role expanded slightly as the show began to tackle heavier themes regarding celebrity scandals and public perception. Tyler’s ability to pivot between the character’s ridiculous pop-star persona and the calculated business-mindedness required by her industry made the character more than just a background joke.
The Recasting: Why Daniele Gaither Took Over
One of the most frequent questions from fans is why Aisha Tyler stopped voicing Sextina Aquafina. In Season 3, the character underwent a major narrative arc involving a faked pregnancy and a controversial music video titled "Get Dat Fetus, Kill Dat Fetus." During this season, the voice was provided by Daniele Gaither.
The reasons for recasting in animation are often pragmatic rather than dramatic. While no official "falling out" was ever reported, the most likely causes include:
- Scheduling Conflicts: During the production of BoJack Horseman Season 3, Aisha Tyler was arguably at the busiest point of her career. She was simultaneously starring in Criminal Minds, hosting Whose Line Is It Anyway?, co-hosting The Talk, and continuing her lead role in Archer.
- Narrative Shift: The Season 3 storyline for Sextina Aquafina required a significant amount of singing and a slightly different comedic energy for the "Get Dat Fetus" rap. Daniele Gaither, a veteran of MADtv with a wide range of character voices and musical capabilities, was brought in to handle this more intensive arc.
- Guest Star Status: Unlike the main cast (Will Arnett, Amy Sedaris, Alison Brie), many of the animal characters in BoJack were voiced by guest stars whose availability varied from season to season.
Despite the change, Tyler’s initial performance set the blueprint for the character's attitude and vocal mannerisms, which Gaither maintained while adding her own flair for the character's musical "career."
Aisha Tyler’s Voice Acting Legacy
To understand why Aisha Tyler was cast as a pop-star dolphin, one must look at her broader body of work. Tyler has a distinct vocal presence—commanding, intelligent, and capable of sharp sarcasm. These traits are essential for BoJack Horseman, a show that demands its actors deliver ridiculous lines with absolute sincerity.
Lana Kane vs. Sextina Aquafina
There is a fascinating contrast between Tyler’s most famous voice role, Lana Kane in Archer, and her role as Sextina. Lana is often the "straight man" (or "straight woman") of the group—the most competent, grounded, and frequently frustrated character. In contrast, Sextina Aquafina is the source of the chaos. Playing a character who is essentially a spoiled, trend-obsessed teenager allowed Tyler to flex different comedic muscles than her work on Archer usually permitted.
Analyzing the Character’s Cultural Impact
Sextina Aquafina is not just a joke about dolphins; she is a critique of how the media handles female celebrities. Her most famous moment—though voiced by Gaither—was the "Get Dat Fetus, Kill Dat Fetus" song. This episode, "Brrap Brrap Pew Pew," is considered one of the most daring episodes of television in the 21st century for its blunt and comedic take on abortion rights.
Even though Tyler had moved on by this point, the character she helped build was the only one in the BoJack universe who could have carried that storyline. Sextina’s brand was built on "shock value" and "rebellion," making her the perfect vehicle for the showrunners to explore how the public reacts when a celebrity uses a serious political issue as a marketing tool.

| Character Focus | Establishing the "Pop Star" persona | Political controversy and motherhood arc |
| Vocal Tone | Smooth, detached, "cool girl" energy | Higher energy, satirical rap vocals |
| Relationship to Main Cast | Primarily Princess Carolyn's client | Cultural icon affecting Diane and BoJack |

Technical Depth: Voice Direction in BoJack Horseman
The voice direction in BoJack Horseman, led by creator Raphael Bob-Waksberg and voice director Linda Lamontagne, favored naturalistic delivery over traditional "cartoony" voices. This is why Aisha Tyler was such a strong fit. Her natural speaking voice has a sophisticated quality that made the absurdity of a dolphin being a pop star even funnier.
When recording for animation, actors typically record their lines alone in a booth, often before the animation is even drawn. This means Tyler had to imagine the world of Hollywoo and her character's dolphin-hybrid nature without visual cues. The success of the character in the early seasons is a testament to her ability to build a personality purely through vocal inflection.
The Reality of "Hollywoo" Satire
The naming of Sextina Aquafina is itself a layer of satire. It combines the hyper-feminine "Sextina" (a play on names like Christina) with the brand "Aquafina," highlighting how corporate interests and personal identity are inseparable in the music industry.
Aisha Tyler's portrayal emphasized this commodification. When she voiced Sextina, the character wasn't just a girl who liked to sing; she was a girl who was aware of her brand. As of 2026, this commentary on "the influencer-to-popstar pipeline" remains highly relevant, as social media continues to blur the lines between personal life and public marketing.
