A plushie scientifically designed to make you immediately empty your bladder upon smooching via a mix of special scents and some light hypnotic visuals from its eyes. It was made as an aid for littles with shy bladders, but it also became a popular prank item.
It was pulled off the market briefly after some evidence of it being addictive, and inducing "a strong, near obsessive bond" after only a few uses. However it is back on sale now, possibly because of lobbying by Big Plush™️
