A comedian and longtime voice actor who played a vital role in a beloved children’s cartoon has died at the age of 50.
According to Parade, Jeff Garcia died on Wednesday at a hospital in Southern California. Garcia’s family members said that he was pronounced dead early on Wednesday morning, and that friends and family surrounded him as he was removed from life support on Tuesday night.
Garcia died after suffering several health setbacks and issues. He experienced a stroke a few weeks ago, and was also hospitalized for pneumonia on November 20.
At the time, he improved enough to be discharged after spending time in the hospital, but returned this week with labored breathing. Garcia suffered a lung collapse on Tuesday, making his condition much more dire.

Garcia’s Career and Most Notable Work
TMZ previously reported that Garcia had canceled shows because he didn’t feel well, leading to his most recent hospitalization.
Garcia appeared in several television shows and films during his career, but he was best known as the voice of Sheen Estevez in the “Jimmy Neutron” series. Garcia played the role in the 2001 film “Jimmy Neutron: Boy Genius,” and reprised it for the television show that followed.
“The Adventures of Jimmy Neutron” ran for three seasons on Nickelodeon, and made history as the first cartoon on the channel to be animated with CGI. The Sheen character was extremely popular with fans, and even led to the creation of a spinoff show centered around him, “Planet Sheen.”
“Planet Sheen” once again starred Garcia and ran for 26 episodes across its only season in 2010 and 2011. In addition to his role as Sheen, Garcia also appeared in several films and television shows as a voice actor.
Garcia’s Life Outside of Entertainment
Garcia played Pip the mouse in the 2006 film “Barnyard,” and reprised that role for the spin-off animated series “Back at the Barnyard.” He also appeared in 2006’s “Happy Feet,” as well as both films in the “Rio” franchise.
“Jeff was a special comedian,” Laugh Factory owner Jamie Masada told TMZ. “He had a huge heart and used his success for outreach to the Latino community, helping to inspire young comics.”
Garcia had two children with his ex-wife, and had been involved in charity work. He promoted a charity called Gracie’s Fund to help a young girl who had been shot by her mother. Garcia donated portions of his DVD and CD sales to the girl’s cause, and he helped promote the charity during his stand-up sets.
