If you’ve ever wondered where all those Big Mouth Billy Bass singing fish that flew off shelves in the early 2000s have gone, take a look inside a Flying Fish restaurant. Each location of the southern seafood chain is home to its own Big Mouth Billy Bass Adoption Center, and they’re always accepting new additions to the collection.

According to Atlas Obscura, the gimmick was the idea of Dallas-based restaurateur Shannon Wynne. He opened his flagship Flying Fish in Little Rock, Arkansas in 2002 when the Big Mouth Billy Bass craze was just starting to wind down. As people grew tired of hearing the first 30 seconds of “Don’t Worry Be Happy” for the thousandth time, he offered them a place to bring their wall ornaments once the novelty wore off. The Flying Fish promises to “house, shelter, love, and protect” each Billy Bass they adopt. On top of that, donors get a free basket of catfish in exchange for the contribution and get their name on the wall. The Little Rock location now displays hundreds of the retired fish.

Today there are nine Flying Fish restaurants in Arkansas, Texas, and Tennessee, each with its own Adoption Center. There’s still space for new members of the family, so now may be the time to break out any Billy Basses that have been collecting dust in your attic since 2004.

And if you’re interested in stopping into Flying Fish for a bite to eat, don’t let the wall of rubber nostalgia scare you off: The batteries from all the fish have been removed, so you can enjoy your meal in peace.
