BRANDON, Florida (CBSMiami) – Bay-area residents are getting quite the bathroom surprise that’s literally got them jumping off their toilet seats.

Imagine going to use the bathroom, looking down and seeing a frog!

Marley Mills said this has been a recurring event in her Brandon, Florida home.

“He’s hopping from side to side and I’m freaking out screaming,” she said. “He will be up under here – like squished up.”

Mills said it’s happened to everyone in her family, and at first she got a kick out of it.

“Sat down and noticed there was a frog up under him… scared him to death. I loved it!” she said.

But then it happened to her about seven times in the past two months.

Master plumber James Greco said it’s not uncommon in the Bay area – typically twice a month.

“Almost 99 percent of the time the vermin come through the roof,” he said.

The plumbing vent pipe is their welcome mat, climbing in to look for food or shelter then getting stuck.

Greco says there’s an easy fix. Get mesh or chicken wire, still allowing for venting, and secure it on the pipe with a clamp that can be easily removed for access. He said it’s an instant critter blocker.

“He will be up on the roof this weekend trying to fix it and if that doesn’t work we’re moving,” Mills said.

The Mills family said if the unwanted surprises continue, they’ll hippity hop out of town.
