The gurgling of water in the s-pipe under the bathroom sink was a monster. It needed to be fed bits of lollipop on a regular basis. If it was not fed then Santa Clause would know. Then I would not receive any presents. I was 6 1/2 when I thought this. The monster is probably quite hungry now as it hasn't been fed in over 20 years.
