I’m a sifter of a memorable shape,
You can eat a variety of me, but I can be toxic,
I can cause severe pain if you’re not careful,
And the action I describe could hurt as well.
What am I?
Kidneys filter your blood and are shaped like kidney beans, which you can eat. Red kidney beans contains high amounts of phytohemagglutinin (quite the word, eh?) and can be toxic if not soaked and boiled. Kidney stones can be extremely painful and if a kid knees you in the stones, that would also be unpleasant.
