A hard-boiled egg, a toy car and an unopened tin of peaches are among items fished out of sewers during lockdown.
Northumbrian Water is urging people not to use "their toilet as a bin" with the company battling blockages in the sewerage system.
The firm has listed its top 10 weirdest finds since the coronavirus lockdown began six weeks ago.
The main cause of blockages is still wet wipes, head of wastewater Simon Chyanko said.
"It's beyond belief some of the weird things our teams uncover in our sewer network and we sometimes wonder what people are thinking," he said.
"We know accidents can happen and items get flushed by mistake, but sadly, some customers are using their toilet as a bin to flush things that have no place in our network.
"Blockages can have heartbreaking consequences, from causing people's homes to be flooded with toilet waste to the environment being polluted. It's really not nice to see."
The oddest items were:
- A hard-boiled egg in County Durham
- Socks in Stockton
- A small unopened tin of peaches in South Shields
- A cut up bed sheet close to a prison
- Red tights in North Tyneside
- Potatoes in County Durham
- A pink hand towel in Stockton
- A toy car in Middlesbrough
- A dead fish in Sunderland
- Loo freshener and a toy centipede in Cambois, Northumberland
Northumbrian Water started a Bin the Wipe campaign after finding about 64% of the 15,600 blockages cleared in 2019 were caused by wet wipes.
