Toothpaste

I can understand about sparkly turquoise toothpaste in the sink and on the counter.  Don't like it but understand, I guess.  And can even sort-of get it when toothpaste occasionally ends up on the cabinet doors even the towels.  (Yes, my kids are messy--one in particular).  But in the bathtub??!! Come on kids!  The bathtub is not even next to the sink!

I should be happy that there is evidence of my kids brushing their teeth.  But how much toothpaste is getting on their toothbrushes and in their mouths?
