The singing rubber fish was all that was left after flames tore through MrChippy in Skegness, Lincs.
Owners Gail and Bruce Whetton watched helplessly as their business went upin smoke.
But they were stunned when firefighters asked them: “Have you got a BillyBass, the singing fish…?”
Gail said: “We had a good laugh. Everything else was destroyed but the fishwas singing his heart out.”
“It started singing as a fireman walked past, making him jump out of hisskin,” said a Lincolnshire Fire Brigade spokesman.
