What is the pink stuff that accumulates in toilet?

It's a slimy kind of fungus or mold. You kill it with bleach, and a good flush! Don't mix bleach with any other cleaning products (outside the laundry soap) or you may create toxic fumes that create instant chemical pneumonia! In the toilet however, you will need a scrub brush if it's all the way to pink.
