K.U.
My daughter has done this twice, but that's been it - when it did, we just pulled her out of the tub, fished it out, flushed it, , drained the tub, then scrubbed it down thoroughly with cleaner and bleach and put the toys in a bucket with bleach water. We called it a "code brown". Friend of mine called it "poop soup." Just to let you know you are not the only one!
