Frog in toilet is definitely a thing. Seen it happen with my own eyes.

Had a small frog in my car recently and we couldn’t get it out. We finally found him but he was well done from the heat.

Your friend is fooling with you. Though a snake coming out of the toilet can happen.

We call them lizards here in Florida.

You may want to check that the clean out access to the outside waste line for your house is intact. I did not realize that our house had a double clean out until not long after we had bought our home in The Villages. I was doing yard work & heard water running about 15-20 feet from main cleanout access (white PVC screw top next to house) while my husband was showering. Grass had grown over the spot where the flat cover for the second access had apparently been hit by a lawn mower at some point. There were plastic fragments from the broken cover on closer inspection. Moving the grass, I saw running water at bottom of 4-6" wide round open pipe. No odor or wet ground around opening. We replaced the cap (it sits more or less flush with the ground), & no more of the bugs we had been finding in bathrooms. We were lucky, as larger creatures could have come into house by same route. This situation may not be uncommon, as I reported same type cover damage recently near tee box at one of exec golf courses, with big hole someone could step in if not careful.

I use the blower to clean my house.

Good for you! They are the good guys

That definitely can and does happen. After the second time a frog in the toilet totally freaked out SWMBO, I fixed the issue with a piece of stainless steel screen and a hose clamp on the top of the vent stack on the roof. Then, for additional peace of mind, I did the same to every other vent stack. Problem solved.

Frogs can get into the house through the vent. While replacing my neighbor's vent, I found a tree frog inside it. I have also found two young squirrels in my toilet that came in through the plumbing vent on the roof.

When The Roof Guys did my roof, they put a new covers on the vents with a screen.

Frog came in through toilet
 

All my vents are covered with screening. To my surprise when I lifted the toilet seat, there was a huge frog on the side of the bowl. I slammed the lid and flushed the toilet. I then lifted the lid and he was still there. I slammed the lid again and grabbed the plunger. When I lifted the lid again he was gone. He apparently swam down the toilet drain. I think that’s how he got in too.

Me too. I use a leaf-blower to clean the house of all the empty beer cans, before my wife comes home from visiting family.

Based on this thread, I rushed to my toilet to check for aholes I didn't see any.

Was there a mirror in the bathroom? :p:wave::a20:

I would guess a little clorex toilet bowl cleaner in the water would keep them out. I had a little green one that attached itself to the hood of my car. Stayed on while I was driving around. I had to gently pry it off.

Sounds like a green tree frog. If so, they can slip through the smallest cracks, or if a window/door isn't closed tightly perhaps. We've had them before...no harm no foul...just scares the wife a bit.
