You came across a pack of hunters trying to catch two seals and sell them for leather, meat and fat. You decided to help poor seals and told hunters, that it's unwise to butch such intelligent creatures - it is much more profitable to sell them to the circus. Now, seals complete against each other playing volleyball. The one which proves more intelligent and agile by winning, will be sold to circus, and, as all animals there - will suffer terribly, but hey - that's still better, than dying instantly, isn't it?
