When I'm brave enough to do the same I find loads of stuff under there. As for the fridge...
And Mosi stashes his treasure under the bed. There's usually at least one make up brush under there, but I have found teaspoons, wooden spoons, dischloths and socks under there in the past.
The thing that really gets me is what happens to the stuff you
don't find. When Jaffa and Magpie were kittens, I bought a load of ping pong balls for them (a pack of about 12). I know for a fact I've never thrown any out, so where are they all??????
One by one they went awol and I've not seen any of them for years.
