Question: Eric Jacobson performed the Muppet character who was part of what fictional band?

full_context: Document 1: Animal Boy: Animal Boy is the ninth studio album released by the American punk band the Ramones through Sire Records on May 19, 1986. Due to conflicts within the group, the album features less of lead singer Joey Ramone, both in performing and writing, and less of lead guitarist Johnny Ramone. Bassist Dee Dee Ramone wrote and sang more on this album than previous albums, and Richie Ramone became the first drummer to write songs for the band. The album spawned four singles, all of which charted on the UK Singles Chart. In addition to singles, the band promoted their album by making a music video which parodied the benefit concerts Live Aid and Hands Across America.
Document 2: Bert and Ernie: Bert and Ernie are two Muppets who appear together in numerous skits on the popular U.S. children's television show "Sesame Street". Originated by Frank Oz and Jim Henson, the characters are currently performed by Muppeteers Eric Jacobson and Peter Linz; Oz occasionally performed Bert between 2000 and 2006.
Document 3: Animal (Muppet): Animal is the fictional wild and frenzied drummer of Dr. Teeth and The Electric Mayhem, the fictional band from "The Muppet Show". He is one of The Muppets originally created by Michael K. Frith.
Document 4: The Rock-afire Explosion: The Rock-a-fire Explosion is an animatronic robot band that played in Showbiz Pizza Place from 1980 to 1992, and in various Showbiz Pizza locations between 1990 and 1992 as Showbiz rebranded and the band was steadily replaced by Chuck E. Cheese characters. The show was created and manufactured by inventor Aaron Fechter, creator of Whac-A-Mole, through his company Creative Engineering, Inc. in Orlando, Florida; in addition to overseeing the production of the animatronics, Fechter also provided the voices for several characters.
Document 5: Gorillaz: Gorillaz are an English virtual band created in 1998 by musician Damon Albarn and artist Jamie Hewlett. The band consists of four animated members: 2-D (lead vocals, keyboards), Murdoc Niccals (bass guitar), Noodle (guitar, keyboards) and Russel Hobbs (drums and percussion). These members are fictional and are not personas of any "real life" musicians involved in the project. Their fictional universe is explored through the band's music videos, as well as a number of other short cartoons. In reality, Albarn is the only permanent musical contributor, and the music is often a collaboration between various musicians. Writers and critics have described their music as alternative rock, trip hop, alternative hip hop, electronica, indie, Britpop, dance-rock, rap rock, dub, reggae and pop.
Document 6: Frank Oz: Frank Oz (born Frank Richard Oznowicz; born May 25, 1944) is an English-born American puppeteer, filmmaker and actor. His career began as a puppeteer, where he performed the Muppet characters of Miss Piggy, Fozzie Bear, Animal, and Sam Eagle in "The Muppet Show", and Cookie Monster, Bert, and Grover in "Sesame Street". He is also known for being the puppeteer and voice of Yoda in the "Star Wars" films.
Document 7: Bert (Sesame Street): Bert is a yellow Muppet character on the long-running children's television show, "Sesame Street". Bert was originally performed by Frank Oz. Since 1997, Muppeteer Eric Jacobson has been phased in as Bert's primary performer, like Grover, although Frank Oz still performs Bert occasionally. Bert has also made cameo appearances within "The Muppets" franchise, including "The Muppet Show", "The Muppet Movie", and "The Muppets Take Manhattan".
Document 8: Fozzie Bear: Fozzie Bear is a Muppet character known for his lack of innate and effective comedy skills. Fozzie is an orange-brown bear who often wears a brown pork pie hat and a red and white polka dot necktie. The character debuted on "The Muppet Show", as the show's stand-up comic, a role where he constantly employed his catchphrase, "Wocka Wocka Wocka!" Shortly after telling the joke, he was usually the target of ridicule, particularly from balcony hecklers Statler and Waldorf. Fozzie's characterization was developed by Frank Oz, who performed Fozzie until 2000. Eric Jacobson has since become the character's principal performer.
Document 9: Grover: Grover, also known as Grover Monster, is a puppet character on the popular television show "Sesame Street". Self-described as lovable, cute and furry, he is a blue monster who rarely uses contractions when he speaks or sings. Grover was originally performed by Frank Oz from his earliest appearances. Eric Jacobson began performing Grover in 1998; he has performed the character regularly since 2001, although Oz still performs him occasionally but not usually.
Document 10: Eric Jacobson: Eric Jacobson (born July 25, 1970) is an American puppeteer, best known for performing the Muppet characters Miss Piggy, Fozzie Bear, Animal, and Sam the Eagle for Disney's The Muppets Studio, as well as "Sesame Street" characters Bert and Grover—all roles that he inherited from the characters' original performer, Frank Oz. As of 2015, Jacobson is now Caroll Spinney's understudy for Oscar the Grouch.
Document 11: Kermit the Frog: Kermit the Frog is a Muppet character and Jim Henson's most well-known creation. Introduced in 1955, Kermit serves as the straight man protagonist of numerous Muppet productions, most notably "Sesame Street" and "The Muppet Show", as well as in movies, specials, and public service announcements through the years. Henson originally performed Kermit until his death in 1990; Steve Whitmire performed Kermit from that time up until his dismissal from the role in 2016. Kermit is currently performed by Matt Vogel. He was also voiced by Frank Welker in "Muppet Babies" and occasionally in other animation projects.
Document 12: Virtual band: In music, a virtual band (also called a virtual group, cartoon group, or cartoon band) is any group whose members are not corporeal musicians, but animated characters. Although it mostly deals with fiction, the band itself doesn't fall under that category, as they exist outside a television and film universe. The music is recorded (and, in the case of concerts, performed) by human musicians and producers, while any media related to the virtual band, including albums, video clips and the visual component of stage performances, feature the animated line-up; in many cases the virtual band members have been credited as the writers and performers of the songs. Live performances can become rather complex, requiring perfect synchronization between the visual and audio components of the show.
Document 13: List of Muppets: The Muppets are an ensemble group of comedic puppet characters originally created by Jim Henson. The Muppets have appeared in multiple television series, films, and other media appearances since the 1950s. The majority of the characters listed here originated on "The Muppet Show", a television series that aired from 1976 to 1981. Since then, several more characters have been introduced in other television series, as well as theatrical films.
Document 14: Miss Piggy: Miss Piggy is a Muppet character known for her breakout role in Jim Henson's "The Muppet Show". Since her debut in 1976, Miss Piggy is notable for her volatile diva personality, tendency to use French phrases in her speech and practice of karate. She was also known for her on-again/off-again relationship with Kermit the Frog, which began in 1978 and has been on a hiatus since 2015. Frank Oz performed the character from 1976 to 2000 and was succeeded by Eric Jacobson in 2001.
Document 15: Alvin and the Chipmunks: Alvin and the Chipmunks, originally David Seville and the Chipmunks or simply The Chipmunks, is an American animated music group created by Ross Bagdasarian, Sr., for a novelty record in 1958. The group consists of three singing animated anthropomorphic chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable one. The trio is managed by their human adoptive father, David (Dave) Seville. In reality, "David Seville" was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label. The characters became a success, and the singing Chipmunks and their manager were given life in several animated cartoon productions, using redrawn, anthropomorphic chipmunks, and eventually films.
