The spiky, irritable, yet lovable porcupine pufferfish in Pixar's 2003 animated classic Finding Nemo is named Bloat. He was voiced by towering stand-up comedian and actor Brad Garrett, best known for his long-running television role as Robert Barone in Everybody Loves Raymond.
Garrett brought a distinct booming baritone and a sharp, comedic delivery to the character. Bloat serves as a key member of the "Tank Gang" in the dentist's office aquarium, helping welcome Marlin and Nemo while managing the high-pressure rituals of tank life.
Who Is Bloat in Finding Nemo?
Bloat is a porcupine pufferfish who spends his days trapped in a Sydney dentist's office. Whenever he gets startled, angry, or anxious, his body expands into a massive, spiky sphere—a comedic physical trait that mirrors real-life pufferfish defense mechanisms. Despite his intimidating spikes and booming voice, he's fiercely loyal to his tank mates and acts as a central figure in the group's rituals.
He helps run the initiation ceremony for new tank arrivals, famously presiding over Mount Wannahockaloogie. His character design relies on quick contrasts: he looks menacing when fully inflated, but his personality is warm, theatrical, and occasionally high-strung.
About the Actor: Brad Garrett
Brad Garrett stands six feet and eight inches tall, a physical presence that often matched his loud comedic style on stage and screen. Before joining the Pixar family for Finding Nemo, Garrett built a massive following in stand-up comedy and television.
His voice work relies heavily on timing, deep registers, and sudden shifts from deadpan sarcasm to explosive energy. In Finding Nemo, these traits fit Bloat's personality precisely. When Bloat yells out warnings or panics about the dentist's niece, Darla, Garrett's vocal inflections give the animated fish an unmistakable human frustration.
Beyond Finding Nemo, Garrett has lent his voice to several other major animated projects. You might recognize his vocal work from films like A Bug's Life, Ratatouille, Tangled, and The Proud Family Movie. He also reprised his role as Bloat in the 2016 sequel Finding Dory.
Behind-the-Scenes Casting Facts
Voice casting at Pixar involves months of testing vocal tracks against early storyboards. Interestingly, Bloat wasn't always voiced by Brad Garrett. Early in production, actor Richard Kind was initially attached to voice the character before scheduling changes or creative shifts led the directors to recast the role with Garrett.
Pixar assembled a heavy-hitting cast for the dentist's tank, pairing Garrett with Willem Dafoe (Gill), Allison Janney (Peach), Stephen Root (Bubbles), Austin Pendleton (Gurgle), Vicki Lewis (Deb/Flo), and Joe Ranft (Jacques). This ensemble required distinct vocal profiles so audiences could instantly tell who was speaking in a crowded tank scene. Garrett's ultra-deep pitch carved out a unique acoustic space in the sound design.
