The cubs have already get used the forest lake and its "coast". But before to start playing on the water, you need to thoroughly inspect everything: to nose every stick, to gnaw every twig, to touch every puddle, to check if the water is wet enough today and if the mud is really dirty?
Well, when the work is done, you can completely surrender to games and water procedures, without thinking about anything!
But no matter how exciting the game is, the slightest unknown sound - and the bear cubs immediately disappear! And it is very good - this is how bears should behave in the nature.
