I had a dream that Ken was in an animal enclosure at a zoo playing fetch with a pair of hippos. Things were going ok for a while, but then he was too slow to pick up the stick and one of the hippos charged him, rammed him, and tossed him about like a rag doll.

Naturally, I was horrified. So I got to work designing a safety platform that would protect the stick thrower from the hippos. It involved a circular safety zone in which the thrower could safely move, surrounded by a pressure-triggered "hippo toss" zone. If a hippo stepped into the zone, it would get forcefully pushed up and away from the safety zone.

I was proud of my invention.
