WATCH: Boy Discovers Python Inside Toilet At Family's Home

A five-year-old boy discovered a snake as he went to use the toilet in his family’s bathroom. As he lifted the seat cover, the boy found a 3-foot-long python resting inside the toilet bowl.

The boy was "frantic" after he spotted the snake inside the toilet bowl in his Southern, Essex home in England, according to his mother, Laura Cowell. She told BBC News Monday how shocked her son was of the whole ordeal. Her son discovered the slimy intruder Wednesday during a routine trip to the bathroom.

"He was frantic, and shaking, and I could tell something was wrong, but that was not what I expected," she told BBC.

Cowell said the toilet had been "blocked for several days and the water wasn't draining well."

"I had to use a broom handle to lift the lid, then out popped its head and its tongue came out as well," she told BBC.

Cowell contacted numerous animal control specialists to retrieve and release the python. She got in touch with Ethan Pinion, an expert who worked at the local pet store Scales and Fangs.

Pinion removed the 3-foot royal python snake. He explained that he had never encountered a snake in the toilet during his years on the job.

"I've done many snake rescues in my 10 years, but I've never had one in a toilet before. It's definitely a first for us," he told BBC.

Rob Yeldham, owner of Leigh-on-Sea pet store, also showed up to help.

Old neighbors of Cowell’s moved and discarded some old vivariums in the trash near her home. The snake probably escaped from an old tank and made its way into her pipes from the sewers.

"I think the snake probably escaped and went down their toilet, and ended up in this one, as all the sewers are connected," Yeldham said.

The snake wasn’t in their home for long and pointed out that it was healthy and not underweight, but had gotten scale rot "probably from the bleach." The snake is being treated at his pet store and once it's "in perfect health" it will be "rehomed with someone reputable so he won't end up in a toilet again," Yeldham revealed.

The snake was a three-foot juvenile male python named Reggie who belonged to a man living in Southend.

"The owner moved into his house two months ago. As he lifted the snake's vivarium into the house, the air vent became loose and Reggie managed to knock the vent off during the night and escaped," Yeldham told The Echo.

"Snakes become active during the night and when he escaped he worked his way up to the air vents of the building. He must have taken the wrong turn and ended up in the sewage system of the lady's house and wandered his way into the toilet."

After the ordeal, Cowell explained that she was so "petrified" that she placed weights on her all toilet seats.
