Chuck E. Cheese’s is phasing out its iconic animatronic band, the larger-than-life ensemble that has performed at the kid-friendly pizza chain for decades, in a bid to become more parent-friendly.

An early-phase remodeling of Chuck E. Cheese’s restaurants in San Antonio, Texas, and Kansas City, Mo., includes “a calmer, more inviting” environment, a focus on food and a live stage show. The animatronic band, however, seems to have lost its gig.

“We removed the animatronics in seven locations,” Christelle Dupont, a spokeswoman for the Irving, Texas-based chain, said Wednesday. “We’re testing to see how those remodeled locations do and what parents and kids like and what’s resonating with them.”

Dupont said the animatronic band will be removed in successive remodels but declined to say when.

Chuck E. Cheese’s has 512 corporate-owned restaurants in the U.S. The company is majority-owned and controlled by investment funds affiliated with Apollo Global Management.

Launched as separate animatronic bands in competing pizza chains more than 40 years ago, the current Chuck E. Cheese’s lineup — known as Munch’s Make Believe Band — is the result of a 1984 merger between ShowBiz Pizza Place and Chuck E. Cheese’s Pizza Time Theatre, which had filed for bankruptcy.

The combined restaurant chain soldiered on under the Chuck E. Cheese’s banner, while the ShowBiz band — the Rock-afire Explosion — was phased out and its performers cannibalized to keep the Chuck E. Cheese’s-led band going.

These days, an animatronic Chuck E. Cheese performs as a solo act at most locations, Dupont said.

The band may be getting a little long in the tooth, said Tom Leverton, CEO of Chuck E. Cheese’s. Children, he said, now “have higher expectations of both realism and special effects.”

For some purists, the original Rock-afire Explosion was the height of animatronic bands, inspiring a cult following that manifested itself in animated message boards, musical revivals and a 2008 documentary.

“They are the greatest animatronic rock ’n’ roll band in the world,” said Aaron Fechter, the Orlando, Fla., engineer who created them.

The Rock-afire Explosion included such characters as Billy Bob Brockali, a banjo-playing bear; Mitzi Mozzarella, a mouse chanteuse; and Fatz Geronimo, a gorilla keyboardist and frontman. In addition to designing the characters, Fechter also voiced several of them.

An original partner in ShowBiz Pizza, Fechter retained ownership of the characters and technology for Rock-afire, which began performing at the pizza chain in 1980.

When the chains merged, he kept his copyright but relinquished the “electronically animated soft sculptures,” which continued to perform for the rechristened Chuck E. Cheese’s for several years.

Then, he said, his creations were repurposed to become characters in the Chuck E. Cheese’s band.

“To this day, a lot of my characters are still out there performing with Chuck E. Cheese masks and costumes and voices,” Fechter said. “But not very well because they’re beat up, they’re badly programmed and their showmanship is terrible. It’s an abomination.”

While Chuck E. Cheese’s is phasing out its animatronics, Fechter is putting the band back together in his Orlando shop, tuning up his creations for a new state fair tour.

In 2013, Fechter sent the band to Las Vegas to back up pop star CeeLo Green for a seven-week run. Rock-afire has also made cameos in several recent movies.

“They declare animatronics is dead, but the Rock-afire Explosion is coming back as real performing artists,” Fechter said. “They’re like the Rolling Stones, an old rock ’n’ roll group that’s still as young as they were in 1980.”
