We discovered a puddle of water on our bathroom floor between the toilet and the outside wall. The hose down has a bright blue substance within it. We carefully checked around the substructure of the toilet - no water and no bright blue color. We checked the underground store - no sign of leaks of the bright blue color. It almost appears that the river came from the outside wall but we aren't unmistaken of that. Plumbers and carpenters - any advice on where on earth the water may enjoy come from and what the blue substance is?
Answers:    Check the tank trademark on your toilet. Or make sure the kids (if nearby are kids) werent playing with bowl cleaner. Would lead to chemical burns.
Do you have a bowl cleaner surrounded by your tank?? Many times the container may have a overrun and if you have blue sea in it that would be your answer.
