Norwegian hobby fisherman Bjørn Frilund was in for a shock when he fileted a 5-pound cod he had just caught and found an orange dildo in the fish’s stomach.

"I was astonished," Frilund, 64, told the Local, a Norwegian English language website, on Friday. "It was totally unexpected. I had never seen anything like this before."

While it’s unclear how the sex toy became a meal for the cod, Frilund has a theory: “a frustrated woman on a cruise” chucked the dildo off a ship in the nearby Barents Sea and the fish mistook the sex toy for the fish’s typical prey.

"Fish eat all kinds of different things," Frilund said. "And the dildo looks like what the fish eat. We have a kind of multi-colored octopus in Norway, maybe the cod thought this was one of these and ate it."

Frilund made the discovery April 7, according to local Norwegian paper Andalsnes Avis.  The 64-year-old hobby fisherman said he first noticed two whole herrings inside the fish’s stomach before finding the dildo. He told the paper the dildo was cordless and had a small electric motor. There were no batteries inside.

Frilund said he gave the fish away after he fileted it.
